The focus of this group is on gaining fundamental insight in a variety of aspects of heat and mass transport in vortex flows and turbulence, including its dynamical feedback on the flow. Research interests include turbulence in flatland, transport in 3D turbulence affected by buoyancy and/or rotation for geophysical and environmental applications, particle and droplet dispersion in turbulence, particle transport in rarefied flows, and 3D viscous mixing in microfluidic and industrial applications. The group always combines laboratory experiments, applying modern optical diagnostics, with high-resolution direct numerical simulations to make progress in these fields.
