Computational Fluid Dynamics Laboratory
Oklahoma State University

We are developing advanced computational methods for nonlinear dynamical systems driven by multiscale and multiphysics processes. The systems studied in our lab range from engineering flow problems to geophysical flow problems with different levels of complexities. There is an emphasis on modeling and analysis of turbulent flows across a variety of spatial and temporal scales. More information about our research activities can be found here

We are located at the third floor of Advanced Technology Research Center building on OSU's Stillwater campus (ATRC 303 & 319).
