COMPUTATION OF THREE-DIMENSIONAL VISCOUS TRANSONIC FLOWS WITH THE LU FACTORED SCHEME.

The LU-ADI factored scheme has been successfully applied to solving the three-dimensional, compressible, 'thin-layer' Navier-Stokes equations. The computations are carried out for the slightly supersonic flow over a hemisphere cylinder at high incidence and the transonic flow over a swept wing. To simulate these complicated flow fields, fine grid distributions up to about 200,000 points were used on a new Japanese supercomputer of 1 GFLOPS. The total cpu time for each case was less than two hours. The result for the flow over a hemisphere cylinder at high incidence revealed the detailed structure of the vortical flow field.
