Numerical simulation of viscous flow around an appended submarine model

摘要

A multizone/multiblock coupled RANS equation solver is presented to nu- merically simulate the viscous flow around an appended submarine model at Reynolds number 1 .E7. k-ε two equation turbulenc model together with wall function are used. The resulting finite difference equations are solved by SIMPLEC, ADI. The technique of ri- sing up the bottom surface is presented to overcome radial contraction problem in Carte- sian coordinate system.
