PENDEKATAN COMPUTATIONAL FLUIDS DYNAMICS Oleh:

A good designer of fishing vessels must be able to estimate ship resistances which treat-ment on ship during fishing operations. Such resistances information will be used as the milestones in the main and the auxiliary engine matching in which the chosen engine must be suitable to the needs of thrust at the certain velocity. The magnitude of ship resistance can be determined by some methods e.g. towing tank methods, using ship resistance graph of series ship models on various velocities, using approaching formula from statistic (with regression) and the last by using Computational Fluid Dynamics (CFD). CFD is the most economic in ship resistance study with result almost approaching the manual test. The ship was gillnetter 5 in gross tonnage. Its model was investigated by using numerical simulation of CFD. The data of resistance are processed with ANSYS CFX version 14. The result shows the vessel resistance was 6,43 kN and engine power was 29,76 kW at maximum speed (9 knots). It implys the similiar conclusion by using manual test and approaching formula
