Abstract: The calculations of AF-2 scheme are made by serial algorithm and parallel algorithm on computer''Yinhe-l"for solving axisymme-trical transonic potential equation with large disturbances in the freestream direction and small disturbance in the radial direction. By computations, the convergence of AF-2 is compared with that of SLOR, and the efficiency for parallel algorithm of AF-2 is compared with the efficiency for serial algorithm. Results indicate rhat A.F-2 technique has led to a 3-7 fold improvement in convergence against SLOR. and the computation efficiency by the parallel algorithm of AF-2 is about 3 times higher than that by the serial algorithm of AF-2.
