Abstract:
A numerical method for calculation of two-dimensional, inviscid, steady and unsteady,small-disturbance transonic flows is presented. A monotone switch ADI algorithm is used to solve the governing equation. The a-ppropriate unsteady terms are added to the boundary conditions on body surface and wake. An analytical, asymptotic solution and the nonreflecting far-field boundary conditions are chosen for steady and unsteady case, respectively. A nonumiform mesh spacing and relatively large time-step are allowable. The developed computer program can be applied for solving both the steady and unsteady flows. Hence, it can be more efficient to use.The computational results obtained from the present method for some examples have provided a closer agreement with experimental results compared to other methods.
