EARSM 난류 모델을 활용한 KVLCC2의 유체 성능 해석

Abstract

In this study, Explicit Algebraic Reynolds Stress Model (EARSM) which is based on the existing k-e model has been applied to the flow field analysis around KVLCC2. Existing transport equations for the turbulent kinetic energy and the dissipation rate are used in almost the same form and anisotropy terms of Reynolds stresses are newly considered. 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. Some improved results for mean velocity distribution at the propeller plane have been obtained. Full scale wake prediction has been also carried out and the results were compared with those from full RSM scheme.pation rate are used in almost the same form and anisotropy terms of Reynolds stresses are newly considered.
