This paper describes an application of CFD (Computational Fluid Dynamics) to the computation of incompressible viscous flow around a marine propeller. High Reynolds-number flow around a marine propeller operating in a uniform flow is simulated using a newly developed CFD scheme, which is based on cell-centered, finite-volume method with global conservation property for mass and momentum flux. Governing equations are full Navier-Stokes equations and continuity equation with

... , which are written in boundary-fitted curvilinear coordinate system fixed on a propeller blade. For discretization in space, 3rd-order upwind scheme derived from flux-difference splitting method is adopted for convection terms and 2nd-order central difference scheme for viscous terms, respectively. 1st-order Euler implicit scheme is adopted for the time integration and the resulted discretized equations are solved by Implicit Approximate Factorization (IAF) scheme with high efficiency.
