- Abstract
- The flow topologies of gas and liquid injections into hypersonic crossflow are compared with the flow topology around three-dimensional rigid obstacles in hypersonic flow. Experimental techniques such as oil flow visualization, infrared thermography, a sublimation technique, and high-speed schlieren photography are applied for a Mach 6 crossing flow on a flat plate. The shock system and the vortex system are visualized and discussed for all cases. Pressure ratios for gas injection, momentum flux ratio for liquid injection, and Reynolds number for three-dimensional obstacles are taken into consideration. The effects of nondimensional numbers on the flow topologies are analyzed. Similarities and differences among different topologies are explained by studying the vortical structures, making use of computational fluid dynamics simulations
