Application of EARSM for prediction of ship hydrodynamic performances

Abstract

In this study, EARSM (Explicit Algebraic Reynolds Stress Model) which is based on the existing k-e model has been applied to the flow field analysis around ship hulls. Existing transport equations for the turbulent kinetic energy and the dissipation rate are used as nearly same form and anisotropy terms of Reynolds stresses are newly considered in the formulation. Target hull forms for a validation are selected as wellknown KVLCC2 and KCS. In case of KVLCC2 double model, comparison of mean velocity distribution, turbulent kinetic energy, and Reynolds stresses near the propeller plane has been carried out and wave elevation and wave profiles have been additionally studied for KCS with free surface models.ssipation rate are used as nearly same form and anisotropy terms of Reynolds stresses are newly considered in the formulation.
