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 … WebIn the present work, ship propulsion performance at different trim angles are investigated. CFD method with dynamic overset grid technique is used to direct simulate the free running ship model. The self-propulsion with design ship speed Fr=0.20 is
