Abstract: A LU TVD scheme is applied to calculate the unsteady flow around a pitching oscillatory airfoil. The results given by this paper are in good agreement with experimental results. Application of different CFL numbers show that using less CFL number can describe the unsteady course more detaily and has higher reliability.
