7. Calculation of Added Resistance in Waves by Rankine Source Method

概要

論文の詳細を見る
The Rankine Source Method is applied to the calculation of added resistance in waves. Introducing a small numerical damping which is equivalent to the artifice due to Rayleigh, a new radiation condition for unsteady flows is developed. The error due to the numerical damping is estimated. The most suitable value for the numerical damping is determined so as to minimize the error. Some analysis of the accuracy of the numerical scheme is performed. Numerical results concerning added resistance of a hemisphere and a blunt ship are presented. The interaction between waves and steady flow around the ship's hull significantly affects these numerical results and it can be estimated by means of the above mentioned scheme.
