SIMULASI NUMERIK TAHANAN KAPAL GILLNET MENGGUNAKAN PENDEKATAN COMPUTATIONAL FLUIDS DYNAMICS
Abstract: 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
themilestones in the main and the auxiliary engine matching in which the chosen
engine must besuitable to the needs of thrust at the certain velocity. The
magnitude of ship resistance can bedetermined by some methods e.g. towing tank
methods, using ship resistance graph of seriesship 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
inship resistance study with result almost approaching the manual test. The
ship was gillnetter 5in gross tonnage. Its model was investigated by using
numerical simulation of CFD. The dataof resistance are processed with ANSYS CFX
version 14. The result shows the vesselresistance was 6,43 kN and engine power
was 29,76 kW at maximum speed (9 knots). Itimplys the similiar conclusion by
using manual test and approaching formula.
