Abstract

The time-dependent evolution of flow around a 120° blunt cone model with a base radius of 60 mm has been visualized at Mach 8.8 and 9.2 using the newly established high speed schlieren facility in the IISc hypersonic shock tunnel HST2. The establishment and termination process of hypersonic flow in the shock tunnel is visualized using both argon and air as test gases. The experimental shock stand-off distance around the blunt cone matches well with the results from the computational fluid dynamics study.
