‘Tears of wine’ influence bubble dynamics
How hydrogen bubbles form and behave on electrodes seems to depend on the anions in your electrolyte, researchers explain from Leiden and Twente in Nature Chemistry.
Flow for future - JMBC report

Fluid dynamics good for 19,000 jobs

More than 19,000 people work on flows in Dutch industry. The export of products and services in the field of fluid dynamics provides great added value for the economy and society. This is evident from the report 'Everything flows in the Netherlands' that was presented to Members of Parliament today. Fluid dynamics is the science of moving fluids, gases and particles and involves predicting, controlling and measuring flows at any speed and on any scale: from the smallest blood vessels in our bodies to hurricanes in the atmosphere. It is a vital, but generally somewhat unknown technology. It appears that more than 19,000 people work on fluid dynamics in Dutch industry and that fluid dynamics contributes 11.5 billion euros to the Dutch economy every year. Fluid dynamics is therefore of crucial importance for solving future societal challenges. In the report 'Everything flows in the Netherlands', which was commissioned by the J.M. Burgerscentrum, the national research school for fluid mechanics, the gross added value is calculated at 130,000 euros per employee. More than 75% of the fluid mechanics industry exports its products and services. The report was presented today to spokespersons for science and innovation in the House of Representatives. The report comes at an important time. The Ministry of Economic Affairs and Climate Policy is working on determining the most important key technologies for the future of the Netherlands. And the Ministry of Education, Culture and Science is also working on a futures study at the initiative of Minister Robbert Dijkgraaf. “Fluid mechanics sometimes fall through the cracks: at OCW people see it more as a technology, at Economic Affairs it is seen as a scientific discipline. Fluid dynamics is therefore structurally underfunded in the Netherlands, while we are demonstrably among the top on a European scale,” says Professor Detlef Lohse (University of Twente), who recently received his third Advanced Grant from the European Research Council ERC. Professor Ruud Henkes, director of the Burgerscentrum: “Internationally, the Netherlands has been regarded as a world leader in fluid dynamics for more than a century. It seems as if other countries appreciate the important Dutch contributions more than the Netherlands itself.” With the report 'Everything flows in the Netherlands', the Burgerscentrum wants to highlight not only the quality but also the importance of fluid dynamics. The report contains appealing examples of results in the areas of climate, energy transition, health, high-tech, environment, agriculture and food. “It is precisely the breadth in the applications of fluid mechanics that seems to be our bottleneck,” says Henkes, “the field really transcends top sectors and missions.” Download the report here in Dutch and in English.

Interview Detlef Lohse - Het is een voorrecht een onderzoeksvoorstel te mogen schrijven

ERC Advanced grant for Detlef Lohse
Detlef Lohse received a grant for his research Melting and dissolution across scales in multicomponent systems.
ERC Proof of Concept grant for Alvaro Marin: Novel technology for detecting and identifying traces of micro and nano plastics in consumable water
Micro and nano plastics are everywhere: in the air, in seas and rivers, in soil, and in plants and animals. The use of plastics in various products is increasing their concentration. The growing presence of micro- and nano plastics in water is a growing problem worldwide. While there is no complete clarity on the harmfulness of these plastics to humans and the environment, there are serious concerns among scientists. UT researcher Dr Alvaro Marin, who is an associate professor in the Physics of Fluids group in the University of Twente’s Faculty of Science and Technology (TNW) is working with colleagues on a technology for detecting and identifying traces of micro and nano plastics in consumable water.
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.
