Large-scale Numerical Simulation, Visualization, and Analysis of Geophysical and Biological Fluid Dynamics

The Yuen group’s research addresses fundamental problems in geophysics, basic fluid dynamics, and biomedical sciences. Many of the complicated phenomena with fine features must be visualized at high resolution in order to fully understand the nonlinear processes inherent in flow problems. For this reason, the research requires the use of Supercomputing Institute resources.

The specific research areas include large-scale simulation and visual computing and feature extraction of coherent features from complex datasets, such as: three-dimensional mantle convection with multiple phase transitions; two-dimensional and three-dimensional tsunami wave modeling and earthquake wave propagation; discrete-particle modeling as applied to multiphase fluid dynamics in blood vessels and growth of blood-vessel networks; interactive visualization of three-dimensional mantle convection and data mining of geological and biomedical data with high dimensionality; and large-eddy simulation of coherent structures in turbulent flows. The group has also recently begun investigating the applications of Graphics Processing Units for visualizations and solutions of partial differential equations.
