Numerical Analysis

The research program of the Numerical Analysis group of TUD belongs to the field of computational science and engineering. We concentrate on the development and application of computing methods to the applied sciences. The focus is on mathematical models relying heavily on partial differential equations, such as occur in fluid dynamics. But we also consider similar mathematical models arising in other fields, for instance materials science, electro-magnetic problems, mechanical models, financial engineering, and reservoir engineering, usually in cooperation with domain experts. A specialty is problems involving partial differential equations with moving internal boundaries, such as occur in bubbly flows and in phase transition problems. To diminish computing time in large-scale applications, iterative methods for solving large systems of algebraic equations are developed further, using deflation, multi-block, preconditioning and multigrid techniques. Furthermore these methods are implemented on the newest computer architectures as there are: Beowulf clusters, multi-core processors, grid computing and GPU's. For our group the collaboration with the other group of the Delft Centre for Computational Science and Engineering ( DCSE ) is of primary importance See also this link for a more elaborate description of Numerical Analysis.

Why doesn't it work and can it be fixed?

Everyday annoyances: the hoover that suddenly stops working, the washing machine that refuses to spin. Or, a small disaster for the at-home worker, the coffee machine that refuses to give you fuel. And yes, of course you can order a new one, but if you want to contribute to a circular economy, you might also want to see if there is anything that can be repaired. PhD researcher Beatriz Pozo Arcos studied how easily defects in household appliances can be diagnosed, and how design can help users do this.

The many angles of technology and human centred design

From an early career in experimental psychology to Professor of Informational Ergonomics at TU Delft’s Faculty of Industrial Design Engineering (IDE), Professor Huib de Ridder has learned that there are a lot of ways to look at things. But one point has always remained central: it all begins with the human.

Bubble Games: can we design for empathy?

Building a better society is no solo endeavour. It needs people to join forces and tackle problems together. But this can only happen if there is a foundation of trust and understanding. In an increasingly polarised world, a group of Dutch designers asked whether it possible to create this strong foundation? Can we design for empathy?

Handling stress: using wearable technology to help people with PTSD

The obvious triggers of stress are all around us: pressing deadlines at work, children not sleeping through the night, a leaking roof. But sometimes it's smaller things, certain locations or specific times of day, that increase our stress levels. Understanding those triggers using wearable technology, with a focus on people who experience a lot of stress - people with PTSD - was the topic of Xueliang Li’s PhD research.

Circular composites - design is the missing link

Composite materials have a lot to offer in terms of fine-tuning material properties, optimising functionality, and ensuring a long-life span. Despite those advantages, they still leave a lot to be desired when it comes to reuse and recycling. For his PhD, Jelle Joustra explored strategies for making composite materials that support a circular economy, proposing that design is the missing link.

Using sensors to stop sports injuries

All athletes, from amateurs joggers to elite footballers, experience sports injuries. What if medical professionals could predict when those injuries were going to occur and stop the damaging activity before the injury happens? In her PhD research, Annemarijn Steijlen takes a step in that direction.

IDE starts to beat in the heart of DHPC Quantum Computer

As of this January the Faculty of Industrial Design Engineering (IDE) has joined the Delft High Performance Computing Centre (DHPC) and the Delft Institute for Computational Science and Engineering. How can this ‘super (computing) power’ be used for design research, to advance visualisations, optimise 3-D printing techniques and solve societal issues and more? What effect could this have on the role of designers? What new areas of research could be addressed? And what implications could this have on ethical issues?
Gebotteld water

From bottled water to doctor

Most people, according to PhD candidate Mirjam Visser, say they want to shop sustainably but few consumers actually purchase the most environmentally-friendly option when shopping. For her thesis research, she set out to understand why some consumers will buy green options while others won’t - and how to encourage people to make more sustainable choices.

What trees teach us about sustainable production of materials

Trees are excellent teachers when it comes to making materials for load-bearing structures with as little resources and energy as possible. One of their secrets? When a tree grows, the direction of the wood grain adapts itself to fit the load that part of the tree is going to bear.

TU Delft jointly wins XPRIZE Rainforest drone competition in Brazil

TU Delft jointly wins in the XPRIZE Rainforest competition in the Amazon, Brazil Imagine using rapid and autonomous robot technology for research into the green and humid lungs of our planet; our global rainforests. Drones that autonomously deploy eDNA samplers and canopy rafts uncover the rich biodiversity of these complex ecosystems while revealing the effects of human activity on nature and climate change. On November 15, 2024, after five years of intensive research and competition, the ETHBiodivX team, which included TU Delft Aerospace researchers Salua Hamaza and Georg Strunck, achieved an outstanding milestone: winning the XPRIZE Rainforest Bonus Prize for outstanding effort in co-developing inclusive technology for nature conservation. The goal: create automated technology and methods to gain near real-time insights about biodiversity – providing necessary data that can inform conservation action and policy, support sustainable bioeconomies, and empower Indigenous Peoples and local communities who are the primary protectors and knowledge holders of the planet’s tropical rainforests. The ETHBiodivX team, made of experts in Robotics, eDNA, and Data Insights, is tackling the massive challenge of automating and streamlining the way we monitor ecosystems. Leading the Robotics division, a collaboration between TU Delft’s Prof. Salua Hamaza, ETH Zurich’s Prof. Stefano Mintchev and Aarhus University’s Profs. Claus Melvad and Toke Thomas Høye, is developing cutting-edge robotic solutions to gather ecology and biology data autonomously. “We faced the immense challenge of deploying robots in the wild -- and not just any outdoor environment but one of the most demanding and uncharted: the wet rainforests. This required extraordinary efforts to ensure robustness and reliability, pushing the boundaries of what the hardware could achieve for autonomous data collection of images, sounds, and eDNA, in the Amazon” says prof. Hamaza. “Ultimately, this technology will be available to Indigenous communities as a tool to better understand the forest's ongoing changes in biodiversity, which provide essential resources as food and shelter to the locals.” . . . .

Moving the Closet

You simply cannot miss it, it is big and magenta: the Pink Closet . On 12 November 2024 the Pink Closet will head to the Main Hall of the TU Delft Library for the first time! The Pink Closet will take its place at the Nook, where it will feature as part of the Studium Generale programme on loneliness. More information on events that coincide with and incorporate the Pink Closet at TU Delft Library will soon be available on the website of Studium Generale .

Green ammonia remains a challenge, but researchers make significant progress

The production of ammonia, essential for fertiliser production, is responsible for almost 1.5% of global carbon emissions. This needs to be greener, which is why researchers have been looking for sustainable alternatives for years.
