Influence of grid type and turbulence model on the numerical prediction of the flow around marine propellers working in uniform inflow

► Numerical predictions of the flow around a model scale propeller. ► Similar accuracy of propeller performance predictions with hexa-structured and hybrid-unstructured meshes. ► Local flow details better captured with hexa-structured mesh. ► Hybrid-unstructured mesh more diffusive than hexa-structured mesh. ► Similar results using the BSL-RSM or the SST turbulence model.
