Abstract

We consider the settling of particles in the presence of a stably stratified temperature or salinity field. Scenarios are discussed under which double-diffusive and Rayleigh-Taylor instabilities can develop, and we demonstrate the existence of a novel, purely settling-driven instability. Both linear stability analysis and direct numerical simulations are employed in order to elucidate the competition among these instability modes.


Biography

Eckart Meiburg received his PhD in Mechanical Engineering at the University of Karlsruhe in Germany. After a postdoc at Stanford and faculty positions at Brown University and USC, he joined the Mechanical Engineering faculty at UC Santa Barbara in 2000. He has held visiting positions in Switzerland, France, Germany, Australia and the U.S. He is a fellow of the American Physical Society and the American Society of Mechanical Engineers, and he currently serves as chair of the Division of Fluid Dynamics of the APS.
