Abstract

A high pressure ratio fan stage, designed under NAL-CAE collaborative programme, has been subjected to 3-D CFD flow analysis using a turbomachinery flow code called Dawes code. Computations have been carried out for three speeds namely 100%, 60% and 50% design speed. For each speed, seven to ten points have been obtained on the performance curves. The flow details have been studied with the help of Mach number contour plots and velocity vector plots. The present computed results at the design speed are also compared with the results from another CFD analysis carried out at BUAA (China) for the same fan stage. Computations at the off-design speeds of 60% and 50% are compared with the experimental data
