Application of Steady State and Transient IR-Thermography Measurements to Film Cooling Experiments for a Row of Shaped Holes

Abstract: This paper presents experimental investigations for the measurement of the adiabatic film cooling effectiveness as well as the heat transfer coefficient distribution in film cooling experiments with a row of fanshaped holes on a flat plate. The temperature distribution on the flat plate is measured using infraredthermography (IR). Adiabatic wall effectiveness data are obtained using a high-temperature plastic material. Although a low thermal conductivity material is used, the measured temperature distribution … Show more

“…In particular, coolant temperature decreases from plenum to hole exit due to heat transfer with the plenum and the hole sidewall (Brauckmann and von Wolfersdorf, 2005). So, basically, temperature of the coolant is supposed to vary with hole position, even if the plenum temperature is uniform.…”
