EVALUATION OF INTERCEPTOR DESIGN TO REDUCE DRAG ON PLANING HULL

A planing hull is a high-speed craft with relatively complex hydrodynamic characteristics. An increase in speed can induce significant change trim angle an increment ship drag. One solution to reduce resistance use interceptor. This research aimed analyze the hydrodynamics of vessel by applying The fundamental aspects reviewed included analysis drag, trim, heave, and lift force. interceptor would be investigated on basis its integrated position at height. also used computational fluid dynamic (CFD) method calm water conditions. All simulations were conducted same mesh structure, which allowed performance evaluation calculating turbulent air–water flow around ship. Numerical calculations Reynolds-averaged Navier–Stokes (RANS) equation k–ε turbulence model predict flow. vertical motion was modeled using fluid–body interaction (DFBI) domain through overset technique. numerical approach compared experimental test results Park et al. ensure accuracy results. designed transition phase, showed highest followed high experience negative speeds; thus, it not recommended. indicated that most effective Froude number 0.87 close chine height 100%. could maximum 57% 17% 8.48% 0.12% excessive drag numbers over 1.16. proved remarkably useful control reduction, but selecting wrong dimensions positions endanger simulation performed Aragon-2; may possibly if different geometry used.
