N2 - A numerical and experimental study is conducted for understanding the effects of an off-axis laser discharge upstream of an ogive cylinder at Mach 3.4. The time dependent numerical study is conducted with AeroSoft Inc.’s GASPex Version 5.3.1 using perfect gas model for laminar and turbulent flow. For the experimental study Stereoscopic Particle Image Velocimetry (SPIV) measurements are performed after a laser energy spark is created with an infrared laser source. The physics of the interaction of the shock wave and heated region caused by the laser discharge with the shock wave of the cylinder is explained. The streamwise and the vertical velocity measurements from SPIV results and the numerical simulation are compared.
