Numerical Simulation of Compressible Viscous flow Around The Moving Airfoil By RANS Method

Simulation of turbulent flows is one of the most important issues that engineers has forced with serious challenged about it. This type of flow simulation requires high computational cost and time. Airfoils have many applications in industry, including turbomachinery rotor blades and propeller aircraft. Two-dimensional and three-dimensional Studing flow around an airfoils that show many properties of flow is important. This article is studying about and solving the compressible flow which is density-based around two-dimensional airfoils and three-dimensional propeller by same section for the fixed two-dimensional case and rotating airfoil in the rotation condition with the velocity inlet and for three-dimensional rotation with velocity inlet for RANS method with Spalart-Allmaras,RNG,SST,RSM. For rotating airfoil added swirling equations using C programming has been to the momentum equations source term. In the two-dimensional pressure coefficint and skin friction of particular importance for the RANS methods for different angles of attack and different models for propeller three-dimensional contour speed during the formation of vortices and extracted.
