TU Delft Institute for Computational Science and Engineering

TU Delft Institute for Computational Science and Engineering (DCSE) About DCSE Computational Science and Engineering (CSE) is rapidly developing field that brings together applied mathematics, engineering and (social) science. DCSE is represented within all eight faculties of TU Delft. About forty research groups and more than three hundred faculty members are connected to, and actively involved in DCSE and its activities. Over 250 PhD students perform research related to computational science. CSE is a multidisciplinary application-driven field that deals with the development and application of computational models and simulations. Often coupled with high-performance computing to solve complex physical problems arising in engineering analysis and design (computational engineering) as well as natural phenomena (computational science). CSE has been described as the "third mode of discovery" (next to theory and experimentation). In many fields, computer simulation, development of problem-solving methodologies and robust numerical tools are integral and therefore essential to business and research. Computer simulations provide the capability to enter fields that are either inaccessible to traditional experimentation or where carrying out traditional empirical inquiries is prohibitively expensive. Mission DCSE’s mission is to take up a leading role in simulating and modelling physical, environmental and social phenomena using computational techniques. The institute is an authoritative community on computational science and engineering-related research, education and strategic cooperation. We are active within TU Delft and beyond: we focus on peers, industry, universities and knowledge institutes worldwide. Vision As society, we face important social and engineering challenges. DCSE contributes to addressing these challenges. From a computational science point of view, four ingredients are crucially needed: (1) a deep and thorough understanding of underlying phenomena; (2) mathematical approximations, efficient algorithms, smart computer simulations and high-end computing resources; (3) a holistic approach to engineering, where people from different backgrounds and with different perspectives cooperate; (4) a well-trained and skilled ‘next generation’ of researchers, engineers and developers. Strategy We connect all researchers who work on enabling technology for industry, and intensify cross-faculty research and cooperation. Our broad education portfolio geared towards the engineer of the future is designed for both bachelor, master, doctoral students, postdocs and staff. With the development of the Delft High Performance Computing Centre, we meet the enormous need among researchers and students for high-end computing resources. An emerging trend is a closer cooperation between CSE and AI, both in improved simulations and in the development of highly efficient algorithms that can be used in both CSE and AI.

NWO grants funding for innovative research on physical experimental environments

How to move from experiment to mainstream? A consortium led by professor Tamara Metze, has been awarded a prestigious grant from the Netherlands Organisation for Scientific Research (NWO). In search for pathways toward more sustainable futures, Metze and her team will explore how various innovations in field labs such as The Green Village, in urban living labs such as Engy Lab South-East in Amsterdam, and in all sorts of citizens’ initiatives, can be mainstreamed and make more impact on sustainability transitions. Pilot paradox The project ‘From EXperiment to sustainable change: TRAnsformative methodologies for Innovation and learning’ (EXTRA) seeks to overcome a persistent “pilot paradox”. In this paradox, much experimentation takes place but long-term systemic impact remains difficult. Researchers together with all sorts of change makers will synthesise existing knowledge on how to mainstream, upscale, spread, broaden and deepen developed innovations. Tamara Metze: ‘I am excited to unravel what are effective ways of cocreation that lead to mainstreaming the positive changes made in experimental environments. We will figure out how learning and innovation can lead to lasting changes in regulations, policies, and financial systems and the biophysical environment.’ Tamara Metze Read the NWO press release Actionable tools The project is crucial for accelerating sustainability transitions. By refining methodologies for mission-driven experimentation and develop hands on tools for all sorts of change-makers, it will be easier to mainstream the sustainable lessons and innovations. ‘These tools will not only aid grassroots innovators but also influence institutional and organisational structures, ensuring that lessons learned from experiments are better anchored in policies, regulations, and organisations’, explains Metze. The project will employ a transdisciplinary action research approach, bringing together knowledge from various disciplines and policy domains. By co-creating solutions with public and private partners, the research will have an immediate impact. In the long term, the project aims to build a more efficient innovation ecosystem, contributing to more impactful and sustainable outcomes for both society and the environment.

Unusual waves grow way beyond known limits

Waves that come from multiple directions are extremer than extreme. These remarkable deep-sea waves can be four times steeper than what was previously imagined, as is shown in research by TU Delft and other universities that was published in Nature today. A long time ago, stories were told of mysterious rogue waves that materialised out of nowhere and could topple even the largest ships. These waves lost their mythical character when the first rogue wave was recorded at the Draupner platform in the North Sea. In 2018, Ton van den Bremer and his colleagues at the Universities of Edinburgh and Oxford managed to recreate the Draupner wave in the lab for the first time ever, and this opportunity to study freak waves closely produced unexpected insights. Multiple waves push up water New research by the research consortium now shows that these remarkable waves do not break when traditional theories hold they should, the secret behind which lies in how they arise. Ton van den Bremer, expert on fluid mechanics at TU Delft and led the study, explains: “When most people think of waves, they think of the rolling waves you’d find on a beach. The type of wave we studied occurs in open water and arises when waves coming from multiple directions come together. When these waves with a high directional spread converge, the water is pushed upwards, forming a partially standing wave. An example of this is known as a crossing wave. How crossing waves arise Under certain conditions at sea, waves from multiple directions occur. This can happen in a place where two seas meet, or where winds suddenly change direction, as in a hurricane. When waves from two directions meet, a cross wave occurs, provided their directions are far enough apart. The study also shows that the further apart the directions are, the higher the resulting cross-wave. Travelling waves break when they reach a certain limit, this is when they reach their maximum steepness. The study shows that waves with a multidirectional spreading can get as much as 80% steeper than this limit before they start breaking, which means they can get almost twice as high as ‘normal waves’ before they start to break. Travelling wave (l) and a wave with high directional spreading (r) Breaking waves that grow Next, the researchers found another highly unusual phenomenon that defies existing theories, a phenomenon that is unprecedented according to Van den Bremer: “Once a conventional wave breaks, it forms a white cap, and there is no way back. But when a wave with a high directional spreading breaks, it can keep growing.” The study shows that these enormous waves can grow to twice their original steepness while breaking, which is already twice bigger than the conventional limit. Together, the waves can grow four times steeper than previously thought possible. Damage to offshore structures The knowledge that multidirectional waves can become as much as four times larger than was deemed possible can help design safer marine structures. "The three-dimensionality of waves is often overlooked in the design of offshore wind turbines and other structures in general; our findings suggest this leads to designs that are less reliable", says Mark McAllister of the University of Oxford, who led the experiments and is now a senior scientist at Wood Thilsted. Innovative vertical sensors made it possible to take accurate 3D measurements of waves. Innovative 3D measurement method A 3D measurement method developed in the FloWave lab paved the way for these new insights. “Conventional 2D wave measurement methods weren’t up to the task”, Van den Bremer explains, which is why the research group designed a new way to create 3D wave measurements. Ross Calvert of the University of Edinburgh: “This is the first time we've been able to measure wave heights at such high spatial resolution over such a big area, giving us a much more detailed understanding of complex wave breaking behaviour." FloWave Ocean Energy Research Facility in Edinburgh. The circular basin has a diameter of 25 metres and can be used to generate waves from multiple directions. Header image by: Fabien Duboc

Ensuring safe and quick food bike-delivery services in cities

Cyclists rushing to deliver food on time to hungry customers is an increasing problem in cities with the growing demand for fast home delivery services. This surge has resulted in more traffic in bike lanes, contributing to accidents and raising concerns about rider safety. In the framework of SINERGI project researchers like Yousef Maknoon are looking into solutions that will help boost logistic operations that are both efficient and safe. ‘Bike delivery services are a great way to transport goods from A to B in a green manner, replacing delivery cars or vans. These micro-delivery systems can really help make city logistics more sustainable,’ says logistics and modelling expert Yousef Maknoon, who is involved in developing real-time decision models for the SINERGI project. Besides looking into sustainability, the project aims to empower delivery providers to offer cost-efficient services, while prioritising the well-being of riders. ‘We want to help bring down the number of accidents,’ stresses Maknoon. Private and public stakeholders have joined to conduct pilot initiatives in the cities of Amsterdam, Shanghai, Singapore and Copenhagen. Yousef Maknoon Safe routing ‘To improve rider safety, the app automatically provides recommended routes when food delivery riders receive their task, helping them avoid dangerous intersections and busy streets. In Amsterdam, the goal is to develop a map that will show the safety of cycling infrastructure. The map is planned to be enriched with real-time information such weather conditions, busy days, and times of the week to not only improve delivery time prediction but also assess route safety in real time,’ explains Maknoon. ‘But everything depends on the cyclist's willingness to take the safer route. When a rider is paid per delivery, they might not be willing to take a longer route. Especially when they know the area well, it can be tempting to take a shorter route that may not always be the safest option.’ A survey held amongst 300 delivery riders found that they can be nudged to follow the recommended routes when they are compensated financially. Profit versus safety Maknoon: ‘What we also found is that paying an hourly fee, instead of paying per on-time delivery, promotes safer riding behaviour, like Just Eat Take​away does in the pilot in Amsterdam. However, other issues arise because riders might not be so motivated to deliver on time. Then you need other incentives to motivate efficiency among riders. Otherwise, customers might switch to other service providers. This puts the business model which is based on hourly payment and prioritize safety, under pressure.’ It seems now that delivery services need to make a trade-off between profit and safety. ‘With the SINERGI project we want to empower delivery providers to offer cost-efficient services while prioritising the well-being of riders.’ Government regulation Public authorities can, for example, improve road safety by enhancing infrastructure, such as building separate bicycle lanes.’ Delivery providers can introduce incentives for riders that compensate the extra time a longer, but safer, route might take. But this puts pressure on profitability and could cause micro-delivery logistics platforms to struggle or even go out of business. It is likely that government regulation will need to play a role in profit-driven societies, as safety risks being overshadowed. Fair delivery system This is also the case for ensuring a fair delivery system where all customers are serviced, whether they live in the busy city centre or the less densely populated countryside. Otherwise, customers who live farther away may not be serviced, as longer cycling times mean less money for riders when they are paid by commission. Riders can simply reject these orders and choose to deliver only to places where they think they can earn more. Human factor In this digitally connected world, we need to consider the human factor in real-time decision-making. The wellbeing of riders, their working conditions, and their quality of life are also important when we talk about making operational decisions. It is interesting to compare the four cities and how they manage the tension between cost-efficiency and safety, and to see what they can learn from each other. About SINERGI SINERGI is a three-year project that runs from 2023 to 2026. It involves thirteen research institutions, governmental authorities, and companies collaborating on a comprehensive framework to improve sustainable city logistics. The project aims to enable real-time management and strategic planning of efficient, safe and user-friendly delivery services. Besides Yousef Maknoon other researchers from TU-Delft involved are: Shadi Sharif Azadeh (project leader), Gonçalo Correia, Kuldeep Kavta and Dongyang Xia. Read more about the SINERGI project.
