The calculation of steady-state cavitating flows around Supercavitating Underwater Bodies (SUB"s), which consist of a circular disk head (cavitator), a conical fore-body, a cylindrical middle-body and either a boat-tail or a flare-tail, are carried o

Recently supercavitating underwater torpedo moving at high speed (over 200 knots) has been interested for their practical advantage of the dramatic drag reduction. Cavitator located in front of the torpedo plays an important role to generate a natura

An implicit algorithm based on a dual-time pseudo-compressibility method is developed to compute water impact forces on bodies. Flow fields of incompressible viscous fluids are solved using unsteady Reynolds-averaged Navier–Stokes equations. Pseudo

The present work has solved 3D incompressible RANS equations on a rotating, non-orthogonal multi-blocked grid to efficiently analyze a ducted marine propulsor with rotor–stator interaction. To handle the interface boundary between a rotor and a sta
