This paper presents the thermal and flow characteristics of a cold transverse jet, injected at five different angles (alpha = 30 degrees, 45 degrees, 60 degrees, 75 degrees, and 90 degrees) into a hot crossflow with four different blowing ratios (M = 0.1, 0.3, 0.5, and 0.8). Three turbulence models, namely, standard k-epsilon, renormalization group (RNG) k-epsilon, and realizable k-epsilon are tested for obtaining the accurate turbulence model to predict the effectiveness of film cooling. The tested turbulence models were compared with available experimental data in the literature. The results evinced that the RNG k-epsilon turbulence model is the most appropriate among the three. It is also observed that maximum cooling efficiency is obtained at alpha = 30 degrees and M = 0.8.
