摘要
高速双体船因为其较高的航速以及双体船本身的特性,而与一般的低速船舶有着较大的不同,因此一些适用于低速船舶的阻力估算方法在估算高速双体船阻力时,可能产生较大的误差。论文以一艘550t高速双体船为例,利用不同的阻力估算方法与CFD计算软件,对其阻力进行了预报。分别计算粘性阻力与兴波阻力的方法,其预报结果与试验结果较为接近,更适合高速双体船的阻力估算。
Because of the big difference between high-speed catamaran and low-speed ships, estimation of the resistance of high-speed catamaran with the methods used for low-speed ships will result in a serious error. In this paper various methods and CFD software are applied to calculate the total resistance of a 550t high-speed catamaran and compared with model tests. The method, in which viscous resistance and wave resistance is calculated separately, is more suitable to the estimation of the resistance for high-speed catamaran.
