Experimental and numerical investigations were performed to study the effects of high
blowing ratios and high freestream turbulence on sweeping jet film cooling. Experiments
were conducted on a nozzle guide vane suction surface in a low-speed linear cascade at a
range of blowing ratios of 0.5–3.5 and freestream turbulence of 0.6% and 14.3%. Infrared
thermography was used to estimate the adiabatic cooling effectiveness. Thermal field and
boundary layer measurements were conducted at a cross-plane at x/D= 12 downstream of …
