Abstract: The method of pseudocompressiblity is used in solving the three-dimensionalsteady incompressible Navier-Stokes flows。The solution procedure employs the Beam-Warming implicit approximate factorization scheme。The Baldwin-Lomax algebraic tur-bulent model together with the Degani-Schiff modiffication is used for Reynolds-averagedNavier-Stokes equations to numerically simulate the high-incidence, great Reynolds number,vortical flow about a tangent-ogive cylinder the asymmetric numerical results are in goodagreem...
