Fluid-fluid interfaces, bubbles, particles or polymers can drastically affect the macroscopic behavior of fluids. Examples range from complex rheological properties, to slippage at surfaces, to active propulsion.
Multiphase and complex fluids are omnipresent in the food and cosmetics industry, printing, chemical reactors, plastic recycling and biomedical engineering applications.
By means of experimental, theoretical and numerical techniques we study multiphase and complex fluidic systems, such as the evaporation of droplets containing active matter or magnetic density separation of plastic particles. We develop new numerical tools for accurately and efficiently describing these systems, with a focus on the interaction between the small-scale and large-scale physics.
