Research Abstract

The purpose of this research is capturing and analyzing the complex phenomena on three-dimensional flow field induced by discharging shockwaves. Laser Interferometric Computed Tomography (LICT) method using interferometer with laser light source is applied to high-speed and unsteady flow field including shock waves for realizing quantitative and three-dimensional density measurements. LICT method is applied to flow fields induced by discharging shockwaves from inclined two circular nozzles and interaction between discharging shockwave from a circular nozzle and circular rod.
