WebABSTRACT The effects of waves and winds on ship forces, moments, motions, maneuverability, and controllability are investigated for the ONR Tumblehome. The air/water flow computations are carried out using a semi-coupled approach in which the water flow is not affected by air flow, but the air flow is computed assuming the free … WebEngineering. 2016. TLDR. CFD-based method coupling with dynamic overset grid technique is applied to investigate the hydrodynamic performance of the fully appended ONR Tumblehome ship model during selfpropulsion condition and good agreements are achieved which indicates that the present approach is applicable for the self-propulsion …
