Hydrodynamic Analysis of a Model Patrol Boat Hull
Keywords:
Drag coefficient, computational fluid dynamic, virtual fluid domainAbstract
This research was conducted with the intent of determining the drag coefficient and study the hydrodynamic behavior around the external body of a model patrol boathull with the aid of Computational Fluid Dynamic (CFD) software using ANSYS CFX version 17.2. The model patrol boatwas tested with four variations of speed at 16, 18, 20 and 22 knots in a virtual fluid domain. For the purpose of generating a 3D geometry of the model boat hull, SolidWorks software was used. A turbulent model was selected to simulate the flow field around the external body of the one-meter class sail boat. The final result for this researchisthe drag coefficient obtained for all variation of speeds. The validation of the results was done by comparing the drag coefficient value from simulation to the established drag coefficient data obtained from the Marine Technology Center (MTC),Universiti Teknologi Malaysia (UTM) on the exact model of a patrol boat used in the simulation.References
