Local simulation of sloshing jet in a rolling tank by viscous-inviscid interaction method

Abstract In this paper, the local behavior of the jet induced by the fluid impact is studied by a new viscous-inviscid interaction (VII) method. This method is based on the inviscid Eulerian-Langrangian (IEL) scheme implemented by the boundary element method (BEM), but it places additional sources on the wetted walls to model the viscous flow within the thin boundary layer. The volume of fluid (VOF) method is also carried out to compare the numerical boundary-layer patterns. The present method not only shows good agreement with the experimental results but also remains very efficient.
