考虑到船舶设计之初在已知船型参数有限的前提下需要进行船舶阻力计算,提出一种一维船舶阻力计算方法;考虑到船型确定后需要进行精细化的船舶阻力计算,以获取更多的流场信息或相对于一维方法的对比分析结果,提出一种三维船舶阻力计算方法。以具有真实物理水池船舶阻力试验结果的KCS船为例,分别基于一维方法利用NavCad软件和三维方法基于STAR-CCM+软件进行KCS船模型尺度与实船尺度下的船舶阻力计算,2种方法的船舶阻力计算结果与真实物理水池试验结果对比误差均在2%以内,验证了2种方法的准确性和可行性。
Considering that ship resistance calculation is needed at the beginning of ship design while the ship type parameters are limited, a 1D ship resistance calculation method is proposed. Considering that it is necessary to carry out fine calculation of ship resistance after the ship type is determined in order to obtain more flow field information or to compare the results with the 1D method, a 3D ship resistance calculation method is proposed. Taking the KCS ship with the real physical tank ship resistance test data as an example, respectively using NavCad based on 1D method and STAR - CCM + based on 3D method to calculate the KCS ship resistance for model-scale and full-scale. Finally, the calculation results of the two methods are compared with the experimental results, and the errors are found to be less than 2%, which verifies the accuracy and feasibility of the two methods.
