ERC starting grant for Guillaume Lajoinie
The European Research Council honoured the applications of three UT researchers for an ERC 'Starting Grant'. The 'early career' grants go to Dr Guillaume Lajoinie, Dr Tim Segers and Dr Saskia Kelders, who are all part of UT’s TechMed Centre. Each researcher will receive an amount of €1.5 million for a five-year period. A total of 408 starting grants have been awarded in Europe with a total value of €636 million.
Devaraj van der Meer elected as fellow American Physical Society
Devaraj van der Meer, Professor in Physics of Fluids at the UT’s Science & Technology faculty, has been elected as fellow of the American Physical Society. He is the eighth UT researcher receiving this prestigious fellowship.
How to design an optimal wind farm?
Last month, the Netherlands, Germany, Belgium and Denmark announced their intention to increase the number of wind turbines in the North Sea by a factor of ten. The team led by Dr Richard Stevens, a Featured Scientist at the University of Twente, is studying the complexities of wind flow that can occur among so many turbines. Using newly developed computer models, they calculate the optimal layout for new wind farms such as those planned in the North Sea. Wind turbines generate electricity by harnessing energy from the wind. In doing so, they reduce the wind speed in the wake of the turbine. This means that a wind turbine positioned directly behind another wind turbine will generate less power. “With two wind turbines these processes are manageable, but when you have hundreds, things become a lot more complicated,” says Stevens.
UT leidt drie van de zeven 'Perspectief' programma's over virusoverdracht, artrose en duurzamer staalproductie
Drie van de nieuwe en ambitieuze ‘Perspectief’ onderzoeksprogramma’s worden geleid door UT-wetenschappers: Detlef Lohse leidt een programma dat gaat over het terugdringen van virusverspreiding via de lucht, Marcel Karperien gaat onderzoek doen naar nieuwe diagnose en behandeling van artrose en Ton van den Boogaard leidt een Perspectief-programma over het vaker toepassen van schroot in het productieproces van staal. In twee andere programma’s is de UT ook partner. De uitreiking vindt plaats tijdens het TEKNOLOWGY festival op 31 mei.
What happens to CO2 at a depth of three kilometers? More insight into CCS
Marco De Paoli has been awarded a prestigious Marie Skłodowska-Curie (MSCA) Postdoctoral Fellowship. The MSCA program is funded by the European Commission and supports excellent research projects in Europe and worldwide. Marco will team up with Detlef Lohse and other researchers from the Physics of Fluids (PoF) research group. Marco’s project will be on geological sequestration of carbon dioxide. This process is relevant for mitigation of climate change, since emission of carbon dioxide (CO2) produced by anthropogenic activities can be considerably reduced with this technique. CO2 produced from combustion of fossil fuels is captured and injected 1 to 3 km beneath the earth surface. Since it is hard to predict the behaviour of CO2 at those depths, they will perform experiments and simulations to understand the dynamics of the process at the labs of University of Twente.
NWO M grant for Sander Huisman and Claas Willem Visser — Turbulence with custom-made fibers
Particles in turbulent flows are everywhere in nature and industry, from algae in the ocean to paper making processes. Not much is knows about these flows, since the particles have complex shapes whereas research has focused on spheres in turbulence. We will investigate turbulence with complex-shaped particles with new experimental techniques for particle fabrication and flow measurement. This is particularly interesting since emerging research shows that such particles can reduce flow resistance. Therefore, we may discover new routes for optimization of industrial processes and better understanding and control of flows in nature.
Turning nanodroplets into microbubbles
University of Twente researchers have developed an ultrasound-based method to turn nano-sized liquid droplets into gas-filled microbubbles. The technology can have important implications for therapeutic drug delivery and the treatment of tumors. At the University of Twente, the magic often happens at a small scale. This is very true for the research of Guillaume Lajoinie and his colleagues. Lajoinie, assistant professor at the Faculty of Science and Technology, Physics of Fluids, together with assistant professor Tim Segers and Professor Michel Versluis, designed a small chip-like device, shaped like a rectangle, to study the vaporization process of liquid droplets. The device, measuring about one by two centimeters, with two wires attached to one end, turns liquid droplets into gas-filled microbubbles.
ERC starting grant for Sander Huisman - Melting dynamics in turbulent flows
Predicting the melting process of an iceberg or glacier, is often not even close to the actual physics, the difference can be a factor 100. Modelling dynamics is also complex in chemical processes in which several boundary layers play a role. The ‘multiscale’ nature – from micrometers to kilometers – of processes, in a turbulent environment and with interaction at the boundary layers, makes it very complex. With fundamental fluid dynamics as a starting point, Sander Huisman wants to reach a better understanding.

Dertien grensoverschrijdende verkennende samenwerkingsprojecten aan de slag met ElektroChemische Conversie en Materialen
Towards upscaling alkaline electrolysis: Pushing the limits of interfacial transport Prof. dr. D. Lohse, R.G.H. Lammertink, dr. D.J. Krug, M. Odijk, A. van den Berg, dr. J.A. Wood (UT), Helmholtz Zentrum Dresden Rossendorf (DE), Nobian, TU Dresden (DE) Waterstof (H2), geproduceerd met hernieuwbare elektriciteit, kan een integraal onderdeel zijn van onze energiestrategie. Met de huidige technologie kan dit proces echter niet economisch worden uitgevoerd. Dit onderzoeksprogramma zal fundamentele inzichten uit chemie, stromingsleer en engineering combineren om meer efficiënte en opgeschaalde technologieën te ontwikkelen voor waterstofproductie door alkaline elektrolyse door beter begrip van grensvlaktransportlimitaties.
