The vorticity confinement (VC) method was applied to tip vortices shed by edges of wings in order to predict induced drag using far-field integration. The optimal VC parameter was determined by its...

The vorticity confinement (VC) method was used with total variation diminishing (TVD) schemes to reduce possible over-confinement and applied to convected and stationary vortices. The optimal VC pa...

This study presents a physics-based cavitation model solving the coupled Rayleigh–Plesset (RP) and Reynolds (RE) equations in a fully transient environment. Inclusion of the surface dilatational viscosity within the interfacial stress balance of a

In this study the Vorticity Confinement (VC) approach is combined with Total Variation Diminishing (TVD) technique to avoid over-confinement and divergence of upwind secondorder of approximation schemes. The TVD schemes were combined with the first (

In the 'universe' of the general cavitation phenomena the issue of cavitation in bearings, due to its particular application and the mostly non-homogeneous working fluids associated with it, has presented a rather specialized challenge. The present p
