Using a PANS Simulation Approach for the Transient Flow around the Japan Bulk Carrier

• In this study, a partially averaged Navier-Stokes 9PANS) modeling approach developed based on the k-omega turbulence model has been applied to the flow around the Japan Bulk Carrier. Three different meshes have been used for a fixed physical resolution for the PANS modeling. The results are encouraging, with small-scale flow dynamics being allowed to develop on reasonably small mesh sizes, but more studies are required before reliable predictive simulations can be performed.
