Research Description

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.
