STUDI PENGARUH VARIASI BENTUK WAVE-PIERCING TERHADAP HAMBATAN PADA HIGH SPEED CRAFT (HSC) BERLAMBUNG KATAMARAN DENGAN SIMULASI COMPUTATIONAL FLUID DYNAMICS (CFD)
Simulation on towing tank that require large costs, makes the ship’s owner have to pay more to find their ship resistance value. Computational Fluid Dynamics (CFD) can be the substitution to determine the resistance. This research discuss the effect caused by the variations application in wave-piercing forms on the MV. Saint John Paul II catamaran High-Speed Craft (HSC) at service speed to find the smallest resistance value among them. The original model of the ship was obtained during TEEP research visiting program at National Taiwan University. 3D modeling on the wave-piercing variations was using Rhinoceros6 software. Analysis to find the value of resistance was using CFD method with the help of Orca3D and “SimericsMP+ForMarine” softwares. Variation was applied to the wave-piercing only, so it does not change the hydrostatic and stability of the initial model that has been validated. Based on the transient CFD result at the speed of 38 knots, the researcher has obtained the axe bow is having the smallest resistance value with 1101kN, followed by the raked bow, that have 1126,35kN resistance value, and the original bow with 1137,7kN.
