Effect of the compressor cooling on the blades mechanical strength

Abstract

In this Work, he will address to the study of the air flow simulation over a compressor blade and measuring the forces acting on them,so to analyze the Aerodynamic flow over the blade, computational fluid dynamics (CFD) is a powerful method for this simulation.The flow around the compressor blade is studied and analyzed using three types of Materials ( Steel,Titanium Alloy,Aluminum Alloy) with the profile NACA 65-10%,the same operating conditions are applied to compute the performance parameters,i.e. Static pressure, Velocity and the aerodynamic coefficients which are the Lift and the drag,after that we conclude the forces according to these two parameters (Lift and Drag).Then we will address to study the effect of the aerodynamic forces which are by the air flow on the blade surface and its influence on the Von Mises stress and the total deformation to see which of these three materials is better for operating and more powerful and resistant than the two others while the forces are acting on them
