Abstract
A streamwise upwind algorithm has been extended to compute unsteady flows with a moving grid system and applied to compute flows over oscillating wings at transonic Mach numbers. Comparisons have been made between results obtained from this upwind algorithm, using both temporally nonconservative- and conservativeimplicit methods, with the results obtained from a central-difference method, and also with experimental data. The efficiency and practicality of the temporally nonconservative implicit solver are illustrated. Results to show the robustness and accuracy of the upwind method for unsteady computations compared to the central-difference method are presented.
