A flow field around a propfan is obtained through finite difference procedure. Viscous effects are incorporated with a thin layer approximation of the Navier-Stokes equations. An implicit approximate factorization technique is used to solve this boundary value problem. An analytical grid generation by the Poisson's equations is employed. A flow field around an eight bladed propfan in cruise condition with Mach number of 0.8 is calculated for two Reynolds numbers in which one corresponds to laminar boundary layer and the other to turbulent boundary layer. The viscous effects diminish the shock wave on the blade surfaces and moderate the steep change of pressure as was seen in the Euler analysis.
