I'm interested in the dynamics of turbulence and dispersed multiphase flow and the studies are mainly carried out by high-fidelity numerical simulations (DNS, LES). The objective is to understand the dynamics of suspended particles, bubbles, or droplets in a turbulent carrier fluid and the mechanism of the interactions between dispersed phase and fluid phase. Our recent research interests / ongoing projects are:

Ÿ Non-spherical particle in wall turbulence

Ÿ Sedimentation by fully resolved simulations

Ÿ Active particles and navigation strategy obtained by deep reinforcement learning

Ÿ Particle-laden non-Newtonian flows

Ÿ Droplet and evaporation in turbulence

If you are a motivated student interested in these topics, or a PhD student looking for a Postdoc position in a relevant field, please do not hesitate to contact me.
