A numerical simulation has been carried out to investigate the influences of pressure side winglet on controlling tip clearance flow in a low speed axial compressor cascade. The use of Winglet on the pressure-side of a highly loaded compressor cascade is investigated as a way of passive tip-leakage control. Two tip clearance gaps of 1.0% and 1.5% of the blade cord length are used to investigate the effect of tip gap variation on the tip leakage flow over the winglet geometry. Spalart-Allmaras (S-A) model was used in study as RANS turbulence
model. The simulation results for the baseline and controlled blades were compared to experimental data. The numerical results showed that the pressure-side winglet increased the blade loading near the tip so, the strength of tip leakage flow was increased and the aerodynamic performance of a typical compressor blade is deteriorated.
