The objective of the present work is to compute unsteady transonic inviscid and viscous flow fields over a pitching NACA0012 airfoil at various angles of the attack.A new pressure based implicit procedure to solve the Euler and Navier-Stokes equations is developed to predict flowsaround the pitching airfoil with high resolution scheme. In this process, nonorthogonal and non moving mesh with collocated finite volume formulation are used. In order to simulate pitching 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 k - Îµ eddyviscosity turbulence model. The algorithm is tested for inviscid and turbulent transonic aerodynamic flows around pitching airfoil.The results are compared with other existing numerical solutions and with experiment data. The comparisons show that the resolution quality of the developed algorithm is considerable.
