Abstract
The present paper aims to investigate the effect of longitudinal curvature on film cooling performance through a single row of cylindrical holes. Four different longitudinal curvature cases are considered by changing the curvature heights. Detailed film effectiveness distributions are presented for several blowing ratios. The ANSYS CFX has been used for this computational simulation. The turbulence is approximated by a shear stress transport (SST) model. The numerical results are compared with experimental data.
