My researches are mainly focused on unsteady aerodynamics. The vortex interactions over double delta wing and dynamic stall problem over rotating blades have been the subjects of many scientists. I've worked in this line of work for more than four years and, current research on "Dynamic Stall " are analysed by any possible experimental and numerical techniques such as Particle Image Velocimetry (PIV), Pressure Sensitive Paints (PSP), Conventional Pressure Scanner and Computational Fluid Dynamics (CFD). Other researches include double ramp for jet engine inlet and delta wing aerodynamics. My researches cover a wide range of flow conditions ranging from very low subsonic case like (M=0.1) to hypersonic velocity (M=7).
