Abstract/Summary We have implemented Pullin's kinetic theory-based Equilibrium Flux Method [Pullin, J. Comput. Physics, 34:231-244, 1980] on a parallel supercomputer (the Intel iPSC Touchstonde Delta). We study the leeward flowfield of a blunt-nosed delta-wing at an angle of attack of 30 degrees and freestream Mach number of 8.7. The delta-wing sweep angle is 70 degrees. The freestream Reynolds number varies from 100,000 to 1,000,100 and the wing temperature is fixed at 300 K. Computational results are presented for a series of grids for both inviscid and laminar viscous flows. Of particular interest are the vortex and shock structures in the leeward flow that are evident only with the high grid resolution. Some experiences of developing a CFD code for a supercomputer are discussed.
