Research Summary

Yeung's research has primarily focused on the use of high-resolution direct numerical simulations to study the fundamental behavior of turbulent flows, and in collaborative efforts, the use of the simulation data to help produce advancements in theory and modeling. Topics that he has investigated include basic issues in Reynolds number dependence and similarity scaling, mixing with molecular diffusivity effects over a wide range of Schmidt numbers, Lagrangian fluid particles acceleration and dispersion, and the effects of uniform solid-body rotation. These simulations are among the world's largest (64 billion grid points as of early 2008) and are conducted on machines providing tens of thousands of parallel processors at multiple national supercomputer centers supported by the National Science Foundation (NSF). Yeung leads a four-institution Petascale Applications project supported by NSF.
