  • Numerical Analysis of Detached Shock Wave by Cartesian Mesh

抄録

Recently spaceplane has been researched and developed all over the world because they have some advantage for world environment and economy. But they have many aerodynamics problems in development. One of them is shock-shock interaction. These problems may cause serious incidents because the shock wave is known to affect aerodynamics heating and flight performance. Shock wave occur during supersonic flight. Thus, in this research, a cylinder model in used to, analyze detachment shock wave by Cartesian grid.Computationalresult is compared with the experimental data about standoff distance. Through the computations, the accuracy of Cartesian-mesh CFD for supersonic was validated. As a result, it was confirmed that the computational result almost coincided with the experimental data.
