Abstract The method of pseudocompressibility is used in solving the three-dimensionalsteady incompressible Navier-Stokes flows. The solution procedure employs theBeam-Warming implicit approximate factorization scheme. The Baldwin-Lomaxalgebraic turbulent model together with the Degani-Schiff modification was used forReynolds-averaged Navier-Stokes equations to numerically simulate highincidencehigh Reynolds number vortical flow about a tangentogive cylinder. To reproducethe experimentally observed asymmetric vortices, it is found essential to introduce asmall asymmetric geometrical disturbance near the body apex.
