抄録

This paper describes the characteristics of pressure fluctuations in the shock wave/turbulent boundary layer interaction region induced by blunt fin placed normal to the wind tunnel wall. The effects of Mach numbers and fin configurations on the pressure fluctuations are also presented. Experiments were conducted at free-stream Mach numbers of 1.5 to 2.6 for blunt fins having sweepback angles of 0, 15, 30 and 45 degrees, with fin leading edge diameters of 4, 6, 8 and 10 mm, respectively. The results showed that the maximum pressure fluctuation levels near separation at given Mach numbers were a function of fin leading edge diameters and boundary layer thickness. It was also found that Strouhal numbers based on shock traveling frequency, shock traveling region length and free-stream velocity have a constant value of 0.020 for all blunt fin configurations.
