Numerical Analysis on the Effect of Blade Sweep and Lean on the Performance of a Partial Admission Supersonic Turbine

The present study deals with numerical flow analysis to investigate the effect of sweep and lean on the performance characteristics of a partial admission supersonic turbine. The flow analysis was performed for three different angles. The angles of sweep and lean are , , . The results of the flow analysis showed that the efficiency is improved as the sweep angle is increased. However, a sweep angle of was less effective in comparison with the baseline model. The total pressure loss was reduced as the lean angle is increased, but the total to static efficiency was decreased.
