Description
Summary:A time domain solution of the gust airfoil problem is obtained using a high accuracy computational aeroacoustics code to solve the nonlinear Euler equations. For computational efficiency, the equations are cast in chain rule curvilinear form, and a structured multiblock solver is used on a distributed memory parallel computer cluster. To fully investigate the performance of this solver, a test matrix of benchmark problems is computed (two airfoil geometries and four gust reduced frequencies). These results are compared to benchmark solutions both on the airfoil surface and in the flow domain.[PUBLICATION ABSTRACT]
