A study of interceptor performance for deep-v planing hull

Abstract The acting on the planing hull is most complex hydrodynamics simulation. Therefore, an analysis was done to evaluate drag, lift force, and seakeeping in two degrees of freedom (2-DOF) which heave trim. It fundamental aspects overall high-speed vessel. This article focused hydrodynamic performance a complete interceptor configuration that could control motion behavior deep-V calm water conditions. benchmark study undertaken by comparing numerical results with experimental Park at al. Models without interceptors had been analyzed simulation performed using Reynold Averaged Navier Stokes (RANS) describe turbulence model k epsilon based computational fluid dynamic (CFD). In this study, proper applies speed less than Froude number 0.87. Interceptor reduce 21% drag 0.87 also 16% trim 6% 0.58. Nevertheless, applied high such as more 1.16 caused lose effectiveness due producing decisive moment made negative (bow-down) increase total drag.
