Dr. M. Sivapragasam

Associate Professor|Faculty of Engineering and Technology, Department of Aerospace Engineering


My major teaching and research interest has been in aerodynamics. In particular, we are interested in the aerodynamics of low and moderate Reynolds number flows- laminar, turbulent and also those involving laminar-turbulent transition. We investigate these phenomena mainly using computational methods. Our further interest has been in the application of formal methods of engineering optimization to enhance the aerodynamic performance at low and moderate Reynolds numbers.
