In the present work, computational simulations were made using SST turbulence model with Gamma Theta model which available in ANSYS CFX. Multi-trench configuration consists of two trenches together, one wider trench and the other is narrow trench that extruded from the wider one. Multi trench configuration was recessed on C3X vane suction side. Several blowing ratios in the range (0.5:3) were investigated. The results indicate that this configuration increased adiabatic effectiveness as blowing ratio increased. No observed film blow-off at all blowing ratios.
