英文摘要Wind tunnel experiments were conducted at incoming Mach numbers (M infinity) of 2.01 and 2.81 to investigate the interactions between shock waves and weak, moderate, and strong streamwise vortices in a concave channel representing the inward-turning inlet/isolator flow of hypersonic engines. Synchronized high-speed schlieren visualizations and high-frequency wall static pressure measurements were collected to evaluate the steady-state and dynamic characteristics of the global and local flowfields. The interference of streamwise vortices bifurcated the oblique shock wave; the stronger the former, the more severe the deformation of the latter with increasing intensity during downstream development. When M infinity=2.01, moderate and strong streamwise vortices caused the Mach stem in the shock train leading edge (STLE) to bend upstream; when M infinity=2.81, moderate and strong streamwise vortices caused the top- or bottom-wall shock waves in the STLE to bend and bifurcate into multiple shock waves. An increase in streamwise vortex intensity weakened the self-excited oscillations of the shock train and enhanced the pressure fluctuations caused by STLE oscillations. The dominant frequency of the interacting flowfield oscillation was 20-40 Hz, and the dominant wave structure in the shock train oscillated rigidly. These results can inform hypersonic engine inlet development.
