Numerical simulation to the 3-D flowfield s of supersonic diffuser in pressure recovery system

This report presents the time-depended fully implicit LU algorithm, which was used to solve the Navier-Stokes equations with NND difference scheme in numerical simulation to the flowfields of supersonic diffuser in the pressure recovery system. The algebric turbulence model as used to simulate the complicated flowfileds, and the computational result was analyzed for more advanced work.
