Item type:Publication, Access status: with files , The CFD study of rudder-bulb-fin system in changing cambered foil and AOA applied to KVLCC2 tanker(2019-09); 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.Publicationtype: Conference Paper106 552
