Numerical simulation and experiment comparison of the submarine wake with a guide vane

摘要

A RANS solver is presented to numerically simulate the viscous wake of a submarine model with guide vane at Reynolds number 10~7. The k-epsilon turbulence model together with wall function is used. The resulting finite difference equations are solved by SIMPLEC, ADI. The technique of rising up the bottom surface is presented to overcome radial contraction problem in Cartesian coordinate system. The three dimensional body forces are adopted to model the affection of the guide vane. Benchmark numerical calculations have been compared with experimental data, the radial distribution of axial velocity on the propeller disk plane is less than 5
