Turbidity Current Simulation

Turbidity Current Simulation

The image shows a high-resolution, direct numerical simulation of a turbidity current in the lock-exchange configuration flowing over a gaussian bump. The top surface is an iso-contour of the particle concentration colored by the velocity magnitude, the middle plane is colored by the shear stress and the bottom surface height and color represent the deposit profile.

Research Description

Professor Meiburg's research interests lie in the general area of fluid dynamics and transport phenomena. His group primarily employs the tools of computational fluid dynamics (CFD), in particular highly resolved direct numerical simulations, in order to obtain insight into the physical mechanisms that govern the spatio-temporal evolution of a wide variety of geophysical, porous media and multiphase flow fields. Occasionally, his group extends their analyses to address issues of linear stability as well. Frequently, they collaborate closely with corresponding experimental investigations. Some current interests focus on gravity and turbidity currents, Hele-Shaw displacements, double-diffusive phenomena in particle laden flows, and internal bores.
