Abstract

Optimization of iodine injection scheme was conducted in Miki Pulley Co., Ltd. using CFD approach. Variation of the mixing speed as a function of an I₂ jet penetration depth, nozzle expansion ratio, and I₂ injection point are analyzed. It was found that the inherent geometry of our nozzle and I₂ injector affects the I₂mixing process. Influence of a backpressure to the cavity flow condition was also investigated in order to estimate the pressure recovery capability of our diffuser. The normal shock based diffuser efficiency for Mach=2.7 flow was 54.5%.
