Dynamics of particles in non-ideal turbulence

Summary

In the present project we want to investigate the dynamics of particles under non-ideal turbulent flow conditions. In our group at Eindhoven University of Technology we have pioneered the use of high-resolution Direct Numerical Simulations (DNS) to study the dynamics of particle transport in turbulence. The PI has investigated the dynamics of tracers and heavy particles in homogenous and isotropic turbulence, measuring e.g. the preferential concentration of particles, as well as the dynamics of turbulent dispersion [1]. In the present project we plan to investigate three topics. First, we want to investigate how dispersed particles can influence thermally driven turbulence flows. Second, we want to investigate how turbulent stresses can “damage” particles: a particular important issue for algae cells in photo-bioreactors. Additionally, in this project we will also investigate a third much less explored flow condition, in particular how non-continuum flow conditions (rarefied gas) influence the occurrence of thermal instabilities. The activities planned in this project are a continuation of a previously founded project (SH-334-15).
