Resistance Analysis for NPL Hull with Bow Variations using CFD

Latuhorte Wattimury, Antoni Simanjutak

Abstract


Ships must have good performance and economic value. To achieve it, optimum speed is needed with minimal engine power usage so it can increase the efficiency of fuel use. The use of engine power is closely related to the total resistance on a ship. One alternative way to reduce ship resistance is to set the shape of the bow of the ship. This research aims to obtain the resistance of ships with variations in the type of bow shape of the ship. The analysis on this research uses numerical method using CFD. Variations in the modelling using NPL with 4 variations of bow hull. Based on the results of CFD calculations, each model NPL hull is obtained, namely; Model 0 to 4. Referring to the results of the analysis, resistances of the NPL using the model 1 design is the best model for low (Fr=0.2) and high speed (Fr>0.4) and using NPL model 1 and 3 are the best for medium speed (Fr=0.25 to 0.35).
