The CFD study of rudder-bulb-fin system in changing cambered foil and AOA applied to KVLCC2 tanker

The present research is to develop the fin geometry based on an available rudder designed for KVLCC2 tanker in calm water. The improvement of rudder-bulb-fin system is discussed in detail in this paper. The cambered foil that is used in this research is a cambered 4-digit airfoil as a design of the National Advisory Committee for Aeronautics. The mean camber line and thickness have been adjusted and simulated using CFDship-Iowa code to be able to find out the optimal energy-saving devices. The angle of attack is also combined through obtaining its benefit from previous designs. The total resistance by these designs could be reduced a significant percentage amount and improved the propulsive efficiency in comparison with previous designs.
