Abstract
Shock/boundary layer interactions (SBLI) is an undesirable phenomenon occurring in high-speed propulsion system. The conventional method to overcome SBLI is using bleed system however a number of drawbacks are associated with it. This study investigates a novel type of flow control device called micro-ramps, a part of the micro vortex generators (VGs) family that intends to replace the bleed technique. Micro-ramps produce pairs of counter-rotating streamwise vortices which help to suppress SBLI and reduce the chances of flow separation. Schlieren photography, surface flow visualisation and infrared thermog-raphy were used in this investigation. The results revealed the detail flow characteristics of the micro-ramp such as the primary and secondary vortices that helps in understanding the overall flow physics of micro-ramps in hypersonic flow.
