Tom Burdyny

Dr. Tom Burdyny Assistant Professor T.E.Burdyny@tudelft.nl Building 58 Van der Maasweg 9 2629 HZ Delft The Netherlands Management Assistant Roos Roeling +31 (0)15 27 82165 M.A.H.Roeling@tudelft.nl twitter instagram The Burdyny Energy Lab in the MECS Group is focused on researching technologies that are capable of replacing current fossil fuel manufacturing routes with processes that use renewable electricity as an input. These technologies use electricity to form chemical bonds (also known as electrocatalysis). At present, our primary research focus is on carbon-dioxide (CO 2 ) electrolysis, which can convert CO 2 into base chemicals such as CO and ethylene. We take a more engineering approach to the research problem and are focusing on a) scaling-up CO 2 electrolyzers in the lab, b) understanding transport related phenomena occurring inside a CO 2 electrolyzer, and c) assessing the potential impact and operation of H 2 O and CO 2 electrolyzers on our global energy infrastructure. The work is embedded within the e-Refinery Institute. Research group Academic background Thomas Burdyny has a mechanical engineering education in the form of a BEng and MASc from the University of Victoria in Canada. He moved to the University of Toronto for his PhD thesis in photocatalytic and electrocatalytic conversion of CO 2 (under Prof. David Sinton), before beginning a postdoctoral fellow at TU Delft in 2018. In 2019 he opened his research group as an Assistant Professor working to advance the performance and scalability of electrochemical technologies. The research mixture of the group is broad and ranges from operando techniques, catalyst development, electrochemical engineering, and transport analysis of electrochemical systems.

Background I’m a Brazilian PhD candidate. I’ve obtained my Bachelor (2013-2018) and Master (2018) degrees in Mechanical Engineering at UNICAMP, both in numerical simulations (CFD) of multiphase flows. Currently, I’m working on the development of a controlled swirl-flow separator via an experimental approach. Research Optimized Controlled Inline Fluid Separation Petroleum is hardly found pure in nature. Its extraction usually involves large amounts of other components, such as water, gas or solid particles. Currently, around 4 barrels of water are extracted from the wells for each barrel of oil. The oil must be separated from the water to be sent to the refineries, and this is currently achieved by bulky (and extremely expensive) gravitational separators. Cyclones are compact alternatives to separate the phases. However, the high shear stress caused in the oil droplets by the swirling flow inside the element cause their breakup, and may lead to emulsions; conditions that certainly impact the efficiency of the device. A control system is required to adjust the flow conditions inside the separator depending on the upstream conditions to avoid, or at least minimize, such effects. My project is to develop the control algorithm that maximizes the efficiency of an inline swirl separator. To achieve such a goal it is necessary (i) an understanding of the hydrodynamics of the process, and (ii) image the distribution of phases inside the equipment. This will be achieved together with the other (3) students involved in the project. More info about the project can be found in the TOMOCON.eu website.

Students Amos Yusuf, Mick Dam & Bas Brouwer winners of Mekel Prize 2024

Master students Amos Yusuf, from the ME faculty (Mick Dam, from the EEMCS faculty and graduate Bas Brouwer have won the Mekel Prize 2024 for the best extra scientific activity at TU Delft: the development of an initiative that brings master students into the classroom teaching sciences to the younger generations. The prize was ceremonially awarded by prof Tim van den Hagen on 13 November after the Van Hasselt Lecture at the Prinsenhof, Delft. They received a statue of Professor Jan Mekel and 1.500,- to spend on their project. Insights into climate change are being openly doubted. Funding for important educational efforts and research are being withdrawn. Short clips – so called “reels” – on Youtube and TikTok threaten to simplify complex political and social problems. AI fakes befuddle what is true and what is not. The voices of science that contribute to those discussion with modesty, careful argument and scepticism, are drowned in noise. This poses a threat for universities like TU Delft, who strive to increase student numbers, who benefit from diverse student populations and aim to pass on their knowledge and scientific virtues to the next generation. It is, therefore, alarming that student enrolments to Bachelor and Master Programs at TU Delft have declined in the past year. Students in front of the class The project is aimed to make the sciences more appealing to the next generation. They have identified the problem that students tend miss out on the opportunity of entering a higher education trajectory in the Beta sciences – because they have a wrong picture of such education. In their mind, they depict it as boring and dry. In his pilot lecture at the Stanislas VMBO in Delft, Amos Yusuf has successfully challenged this image. He shared his enthusiasm for the field of robotics and presented himself as a positive role model to the pupils. And in return the excitement of the high school students is palpable in the videos and pictures from the day. The spark of science fills their eyes. Bas Brouwer Mick Dam are the founders of NUVO – the platform that facilitates the engagement of Master Students in high school education in Delft Their efforts offer TU Delft Master Students a valuable learning moment: By sharing insights from their fields with pupils at high school in an educational setting, our students can find identify their own misunderstandings of their subject, learn to speak in front of non-scientific audiences and peak into education as a work field they themselves might not have considered. An extraordinary commitment According to the Mekel jury, the project scored well on all the criteria (risk mitigation, inclusiveness, transparency and societal relevance). However, it was the extraordinary commitment of Amos who was fully immersed during his Master Project and the efforts of Brouwer and Dam that brought together teaching and research which is integral to academic culture that made the project stand out. About the Mekel Prize The Mekel Prize will be awarded to the most socially responsible research project or extra-scientific activity (e.g. founding of an NGO or organization, an initiative or realization of an event or other impactful project) by an employee or group of employees of TU Delft – projects that showcase in an outstanding fashion that they have been committed from the beginning to relevant moral and societal values and have been aware of and tried to mitigate as much as possible in innovative ways the risks involved in their research. The award recognizes such efforts and wants to encourage the responsible development of science and technology at TU Delft in the future.

New catheter technology promises safer and more efficient treatment of blood vessels

Each year, more than 200 million catheters are used worldwide to treat vascular diseases, including heart disease and artery stenosis. When navigating into blood vessels, friction between the catheter and the vessel wall can cause major complications. With a new innovative catheter technology, Mostafa Atalla and colleagues can change the friction from having grip to completely slippery with the flick of a switch. Their design improves the safety and efficiency of endovascular procedures. The findings have been published in IEEE. Catheter with variable friction The prototype of the new catheter features advanced friction control modules to precisely control the friction between the catheter and the vessel wall. The friction is modulated via ultrasonic vibrations, which overpressure the thin fluid layer. This innovative variable friction technology makes it possible to switch between low friction for smooth navigation through the vessel and high friction for optimal stability during the procedure. In a proof-of-concept, Atalla and his team show that the prototype significantly reduces friction, averaging 60% on rigid surfaces and 11% on soft surfaces. Experiments on animal aortic tissue confirm the promising results of this technology and its potential for medical applications. Fully assembled catheters The researchers tested the prototype during friction experiments on different tissue types. They are also investigating how the technology can be applied to other procedures, such as bowel interventions.

A key solution to grid congestion

On behalf of the TU Delft PowerWeb Institute, researchers Kenneth Brunninx and Simon Tindemans are handing over a Position Paper to the Dutch Parliament on 14 November 2024, with a possible solution to the major grid capacity problems that are increasingly cropping up in the Netherlands. The Netherlands is unlikely to meet the 2030 climate targets, and one of the reasons for this is that large industry cannot switch to electricity fast enough, partly because of increasingly frequent problems around grid capacity and grid congestion. In all likelihood, those problems will actually increase this decade before they can decrease, the researchers argue. The solution offered by the TU Delft PowerWeb Institute researchers is the ‘flexible backstop’. With a flexible backstop, the current capacity of the power grid can be used more efficiently without sacrificing safety or reliability. A flexible backstop is a safety mechanism that automatically and quickly reduces the amount of electricity that an electric unit can draw from the grid (an electric charging station or a heat pump) or deliver (a PV installation). It is a small device connected or built into an electrical unit, such as a charging station or heat pump, that ‘communicates’ with the distribution network operator. In case of extreme stress on the network, the network operator sends a signal to the device to limit the amount of power. Germany recently introduced a similar system with electric charging stations. The backstop would be activated only in periods of acute congestion problems and could help prevent the last resort measure, which is cutting off electricity to users. ‘Upgrading the electricity network remains essential, but in practice it will take years. So there is a need for short-term solutions that can be integrated into long-term planning. We, the members of the TU Delft PowerWeb Institute, call on the government, network operators and regulator to explore the flexible backstop as an additional grid security measure,’ they said. The entire Paper can be read here . Kenneth Brunninx Associate Professor at the Faculty of Engineering, Governance and Management, where he uses quantitative models to evaluate energy policy and market design with the aim of reducing CO2 emissions. Simon Tindemans is Associate Professor in the Intelligent Electrical Power Grids group at Faculty of Electrical Engineering, Mathematics and Computer Science. His research interests include uncertainty and risk management for power grids. TU Delft PowerWeb Institute is a community of researchers who are investigating how to make renewable energy systems reliable, future proof and accessible to everyone.
