基于Rankine源和Kelvin源格林函数求解兴波阻力的复合算法
Wave resistance calculation method combining Green functions based on Rankine and Kelvin source
摘要
Abstract
[Ojectives] At present, the Boundary Element Method(BEM) of wave-making resistance mostly uses a model in which the velocity distribution near the hull is solved first,and the pressure integral is then calculated using the Bernoulli equation. However,the process of this model of wave-making resistance is complex and has low accuracy. [Methods] To address this problem,the present paper deduces a compound method for the quick calculation of ship wave resistance using the Rankine source Green function to solve the hull surface's source density,and combining the Lagally theorem concerning source point force calculation based on the Kelvin source Green function so as to solve the wave resistance. A case for the Wigley model is given.[Results]The results show that in contrast to the thin ship method of the linear wave resistance theorem,this method has higher precision,and in contrast to the method which completely uses the Kelvin source Green function, this method has better computational efficiency. [Conclusions] In general,the algorithm in this paper provides a compromise between precision and efficiency in wave-making resistance calculation.关键词
