Computation of Rotational Transonic Flow
A pseudo-time dependent, split, explicit finite-volume procedure that captures discontinuities in the solution is applied to Workshop Problem A, B, C and E. The boundary conditions used in the method are described in detail, and special features of the algorithm for dealing with discontinuities are discussed. The slip line following from the trailing edge of the body is considered a discontinuity and captured. No special treatment is employed at the trailing edge. An attempt to condition the underlying matrix problem in order to influence favorably the convergence process produced unsatisfactory results even though the calculation was stable. A solution to Problem B, for which the shock wave was fitted, compares reasonably well with the one in which the shock was captured. Some computational particulars are given for the calculations.
