Abstract

The talk will present our research on fluid dynamics that is beneficial from using acoustic waves as a tool to measure, image, and manipulate the fluid behaviors in low-gravity and ocean environments. In the first part of the talk, I will present fluid control and manipulations in low-gravity environments that play a role in power for human space exploration, in which we combine modeling and experiments to investigate scattering and dissipation of capillary waves at the presence of contact lines, and develop technical approaches using sound waves (acoustic tweezers, acoustic tractor beams) to manipulate fluids on the ground and at the International Space Station. In the second part of the talk, I will present oceanic internal wave modeling and observation, in which we used direct numerical simulation to model internal wave generation by tidal flow over seafloor, and used seismic reflection data from oil industries to observe the spatial-temporal variation of internal waves at the Gulf of Mexico.

Speaker Bio

Likun Zhang is an Assistant Professor of Physics and National Center for Physical Acoustics at University of Mississippi (UM). He received his PhD in Physics from Washington State University in 2012 under the supervision of Philip Marston. He was a postdoctoral fellow and research associate at the University of Texas at Austin working with Harry Swinney, before joining UM in 2016. He received the R. Bruce Lindsay Award from the Acoustical Society of America in 2021. His interests are primarily in the physics of acoustics and wave dynamics in fluids.
