CFD Simulation Verification Processes at Planing Hulls using An Interceptor

Experimental test is one of the methods for predicting drag ships using towing tank. This method has a good level accuracy but requires quite complex equipment and costs. With advancing technology computing, CFD emerged as an alternative problem-solving, especially in hydrodynamics analysis. study aims to ensure Computational Fluid dynamics (CFD) by verifying experimental data on high-speed vessel interceptor. The Interceptor system generates hydrodynamic lift force intercepting flow water under hull. Comparison results numerical simulations will involve analysis drag, heave trim. Numerical were carried out ITTC recommendations testing standards. research uses grid independence mesh. overset mesh k-epsilon solve turbulence flow. Dynamic Body Interaction (DFBI) module employed resolve dynamic motion ship order assess hull movements based fluid forces moments. There can be two degrees freedom pitch directions. All are performed calm condition. Verification reviewing condition without interceptor with 100% stroke 60% used variations verification this study. indicate that been verified maximum error range 10.7%. Planing type fast characteristics. also shows use interceptors proven improve performance planing ship.
