Abstract
The numerical methods and the calculated results of the turbulent flow around two- and axi-symmetric submerged bodies are presented in this paper. The Reynolds-averaged-Navier-Stokes equations and continuity equation are solved. The Baldwin-Lomax turbulence model is employed to simulate the high Reynolds-number flow. Governing equations are discretized using the finite-difference schemes and solved by using the implicit approximate factorization to reduce the computational efforts. The successive-over-relaxation is used to solve pressure-Poisson equation to obtain the pressure field projecting the divergence-free velocity field. Calculated results clearly show the flow characteristics near the stern of the two-dimensional and axy-symmetric body and calculated drag coefficients (CF, CR) show fairly good agreement with the experimental data.
