Dr. Venkat Narayanaswamy is interested in scramjet propulsion, laser diagnostics, and combustion. Prior to joining NC State, he was a Postdoctoral Research Associate at UT Austin and RWTH Aachen, Germany. Dr. Narayanaswamy’s long term vision is contributing to the development of next-generation clean and efficient propulsion technologies.
Outside research, Dr. Narayanaswamy is interested in nature photography.

Dr. Narayanaswamy's research interest focuses on turbulent shear flows, which have common occurrences in several propulsion devices, where he performs laser-based experiments to understand the complex flow interactions that result in several undesirable phenomena like base drag, jet noise, flow separation, and pollutant emissions. He also develops novel plasma-based flow actuators that exploit the non-linear interactions in turbulent flowfield to effect base drag reduction, noise suppression, etc. In the long term, he envisions that these actuators will be integrated into the future propulsion systems.
