LES analysis was conducted to investigate the evolution of turbulent coherent vortices and the interaction and merging phenomenon of vortex by inserting a ring in the idealized hybrid rocket engine. Even though the chemical reaction was not considered, the calculation results can be useful in determining the turbulence characteristics generated by the ring. The calculation results show that the installation of ring (diaphragm) can introduce the additional turbulence and improve the fluctuated motion to the downstream flow. Calculation results revealed to understand the flow dynamics of large scales vortex on the upstream blowing surface and small scales vortex on the downstream blowing surface.
