The expansion corner is a common feature on hypersonic vehicles, which has a significant impact on transition. This study investigates how the expansion corner affects instabilities of Mach 6 swept wing boundary layer flows. Results show that the expansion corner increases the growth rate of the most unstable stationary crossflow mode in this case.
