STUDY ON SEPARATION OF SHIP RESISTANCE COMPONENTS

The paper describes theoretical and experimental studies on the separation of ship resistance components, namely the wave resistance and the viscous resistance. The theoretical analysis gives the asymptotic formulae of both components with linear approximation. The experimental results are analysed by the use of the asymptotic formulae. The sum of both components, each measured separately, is in good agreement with the total resistance measured by dynamometer. The interaction term of these components can be neglected as a higher order quantity. A new resistance component was found from the viscous resistance derived by the wake survey method. The component is caused by the breakdown of bow waves and is much greater than the wave resistance derived by the wave analysis method. A theoretical approach was made to interpret the nature of the new component. ( Author )
