Abstract: The main objective of this study is to analyze the effect of the solid deposits downstream of the injection hole on the film cooling efficiency by highlighting the impact of several geometrical and physical parameters, such as the blowing ratio, deposit position, and deposit height, by using the ANSYS CFX software. Several configurations are tested by changing the deposit position and deposit height. The turbulence is approximated by the shear stress transport (SST) model. The film cooling effectiveness distributions are presented for different blowing ratios. The numerical results are compared with available experimental data, and good agreement is noted.

Keywords: computational fluid dynamics, heat and mass transfer, turbulence, thermal protection, rocket nozzle, film cooling, deposit.
