ON FULL SCALE AND MODEL SCALE CFD SIMULATION OF A PRODUCT TANKER

Abstract

The main purpose of this project is to determine the hydrodynamic parameters such resistance, sinkage, trim and wake of the product tanker using Computational Fluid Dynamic (CFD) modelling software, SHIPFLOW. Not only that, the effectiveness of CFD in determining resistance is also the main aim of this project. The 100m product tanker was simulated in deep water condition at different speed, ranging from 8 to 12 knots and the viscous, wave and total resistance were calculated. Besides that, the model scale was also simulated to obtain the hydrodynamic parameters in corresponding speed respectively. For experimental values, the data for model scale was taken from the towing tank experiment which was conducted by UTM and in UTM Towing Tank facility. Finally, the comparison of CFD values and experiment values was analysed. Experimental investigation appears to provide agreement with computed values and showing that the CFD methods may adequately deal with the problem of wave interference produced by the tanker hull. However, there were some discrepancy in total resistance between CFD and experiment.
