Research Interests:

Steve de Bruyn Kops is a fluid dynamicist whose research emphasizes transitioning and turbulent flows. He is currently studying variable density, density stratified and chemically-reacting flows. His general approach is to run very large direct numerical simulations (DNS) of a flow of interest and to use the results to understand the underlying physical phenomena. He then develops models for those phenomena and tests them against the DNS data sets. With simulations among the largest running on the nations supercomputers, he has demonstrated that DNS can be used to augment specific laboratory experiments in order to take advantage of both the numerical and laboratory approaches to studying fluid mechanics.
