Oleg Goushcha

Assistant Professor

Mechanical Engineering

Dr. Goushcha is an Assistant Professor of Mechanical Engineering. His research focuses on experimental fluid mechanics studying turbulent, transitional and vortical flows. Previous and current work include wind tunnel tests of passive-scalar mixing and energy harvesting in turbulent flows, fluid-structure interaction, and transition to turbulence and relaminarization in pulsating flows. His research is inspired by current needs in the clean technology and biomedical industries. Close interaction between academia and industry drives Dr. Goushcha to provide his students with theoretical tools and their practical applications in the industry.
