Parametric Study of Lift-Drag Coefficients vs. Geometric Parameters of Axial Compressor/Turbine for Flow Blade Interactions

Abstract

This project is a parametric study of the Lift-Drag coefficients from blade hub to tip radius of Axial Compressor/Turbine for flow blade interactions. The study contemplates the effect of Lift and Drag forces varying the inlet blade angle and the response with an actuator Inlet Guide Vane (IGV). In the turbine section, the Lift and Drag forces are also studied varying the inlet blade angle for the rotor and the effect with different exit nozzle angles. Lift force is used to convert energy from the shaft to the fluid and vice versa while drag is the energy losses due to friction. The desired effect was found at lower inlet blade angle. The study was done using the fundamental turbomachinery equations and the compressible flow properties.
