Abstract

Joint experimental / numerical study is performed to specify influence of the single- and double-pulsed laser-induced energy deposition on the bow shock wave and flow field structure in the vicinity of spherically blunted body with a diameter of 60mm at the Mach number of 2. The optical discharge is induced by a focused laser beam penetrating in the upstream direction in front of the hemisphere. Experimental investigations are conducted in the Ludwieg Tube Facility at DLR Göttingen. The numerical calculations are performed in the framework of the unsteady Euler equations.
