Particle-laden Flow

Understanding the dynamics of a range of suspended particles, bubbles, or droplets in a turbulent carrier fluid and the mechanism of the interaction between the dispersed phase and the turbulence fluid phase are of fundamental interest and a key in making advances in many natural and industrial processes.

Our research interests are primarily in the fundamental aspects of dispersed multiphase turbulent flow and its applications in practice, such as sand transport in atmospheric boundary layer and phytoplankton settling in turbulent oceanic flow. In past years, we have been intensively engaged in exploring the physics of particles in wall turbulence and developing high-fidelity numerical technique, such as direct numerical simulation, for turbulent multiphase flow simulations.

The current ongoing research in our group is consisted of three major parts: I. Dynamics of anisotropic inertial particles in wall turbulence. II. Turbulence modulation induced by fluid-particle interaction. III. Active particles suspensions.
