IN MEMORIAM: IRAJ KALKHORAN

As an Associate Professor of Aerospace Engineering, Iraj Kalkhoran specializes in high speed aerodynamics, aero-propulsion, and wind tunnel design and testing. His current research addresses the computational simulation of shock/vortex dominated flows and experimental and computational studies on novel jet-noise reduction schemes via fluidic injection. Past research activities have included topics such as supersonic shock wave and vortex dominated flows and the dynamics of supersonic vortex breakdown as a result of vortices interacting with shock fronts


Since 2007, Kalkhoran has been actively involved in various educational initiatives including curricula development, implementation of advanced technology in teaching and learning, and data-driven enrollment and retention efforts.


In support of his scientific and educational research, Kalkhoran has received funding from NASA, the Air Force Office of Scientific Research, the Army Research Office, Northrop-Grumman, and the US Department of Education.
