Numerical Investigation on Backward-Injection Film Cooling with Upstream Ramps

Numerical Investigation on Backward-Injection Film Cooling with Upstream Ramps

The present study investigates the effects of upstream ramps on a backward-injection film cooling over a flat surface. Two ramp structures, referred to as a straight-wedge-shaped ramp (SWR) and sand-dune-shaped ramp (SDR), are considered under a series of blowing ratios ranging from <i>M</i...
