Abstract

This paper presents a computational study of flow around three-dimensional geometries as the Ahmed body, which is a classical test case for automotive flow, but also as the JBC (Japan Bulk Carrier)which was first investigated in the framework of the Tokyo 2015 Workshop on Numerical Ship Hydrodynamics. For both test cases, an investigation of RANS (\(k-\omega \) SST and EARSM) and hybrid RANS-LES models (DES and IDDES) is conducted. All simulations have been performed with the ISIS-CFD flow solver, which is developed by Ecole Centrale de Nantes and CNRS. For both geometries, the hybrid RANS-LES models predict a high level of turbulent kinetic energy which is in better agreement with the experiments than the quantity predicted with a RANS turbulence model.
