Dr. Cui will study agitated granular flow using a turbulence model and the process of transition this urbulent-like state using catastrophe theory.
Brownian motion of particles in fluid is a common collective behavior in biological and physical systems. In a new report on Science Advances, Kai Leong Chong, and a team of researchers in physics, engineering, and aerospace engineering in China, conducted experiments and numerical simulations to show how the movement of vortices resembled inertial Brownian particles. During the experiments, the rotating turbulent convective vortical flow allowed the particles to move ballistically at first and diffusively after a critical time in a direct behavioral transition—without going through a hydrodynamic memory regime. The work implies that convective vortices have inertia-induced memory, so their short-term movement was well-defined in the framework of Brownian motion here for the first time.

Astronaut conducts Cornell experiment on the space station – Cornell Cronicle, Dec. 16. 2019.
Orbiting 250 miles above the Earth on the International Space Station, astronaut and station commander Luca Parmitano conducted the experiment „Inertial Spreading and Imbibition of a Liquid Drop Through Porous Surface“ designed by Professor Michel Louge, professor of mechanical and aerospace engineering at Cornell university, on Dec. 11. MSS collaborated by developing an experimental technique to produce large fluid drops in microgravity and testing the apparatus in drop tower experiments.
A detailed descripton of the experiment is provided on the project’s web site at Cornell.
