直交格子法を用いたバックステップ流れの流体解析

抄録

The development of solid rocket for the launch of the smaller and lighter has become necessary due to the development of the private space industry. However, pressure vibrations due to vortices may occur in the combustion chamber, causing problems of reduced flight performance and damage of the payload. In this study, we calculated the backstep flow using Cartesian Grid Methods to investigate the effectiveness of the Cartesian-mesh CFD method in the backstep flow.
