Title : ( Simulation of Pitching and Heaving Airfoil with Oscillation of Flow Boundary Condition )
Authors: Mohammad Hassan Djavareshkian , Amirreza Faghihi ,Abstract
A pressure based implicit procedure to solve the Euler and Navier-Stokes equations is developed to predict transonic viscous and inviscid flows around the pitching and heaving airfoils with a high resolution scheme. In this process, nonorthogonal and non moving mesh with collocated finite volume formulation are used. In order to simulate pitching or heaving airfoil, oscillation of flow boundary condition is applied. The boundedness criteria for this procedure are determined from Normalized Variable Diagram (NVD) scheme. The procedure incorporates the eddy-viscosity turbulence model. This process is tested for inviscid and turbulent transonic aerodynamic flows around oscillation airfoil. The results are compared with other existing numerical solutions and with the experimental data. The comparisons show that the resolution quality of the developed algorithm is significant.
