Influence of Different Rim Widths and Blowing Ratios on Film Cooling Characteristics for a Blade Tip
Three-dimensional simulations of the squealer tip on the GE-E-3 blade with eight film cooling holes were carried out. The effect of the rim width and the blowing ratio on the blade tip flow and cooling performance were revealed. Numerical simulations were performed to predict the leakage flow and the tip heat transfer with the k-epsilon model. For the squealer tip, the depth of the cavity is fixed
