Abstract A coupling algorithm is developed to accelerate the boundary element method for both open water and unsteady calculations. It is realized in the way that the full wake alignment is conducted using the vortex lattice lifting line method with discrete wake sheet. Techniques to convert wake sheets of lifting line to those for boundary element method are described. Numerical simulations for open water and unsteady case are then carried out. It shows that the coupling method predicts similar results as the boundary element method, especially for the open water case. Evident reduction of the computational time is also observed, which is 70% and 65% for open water and unsteady calculation, respectively.

开放水域和非定常螺旋桨模拟的耦合尾流对准提升线法和边界元法

摘要 开发了一种耦合算法来加速开放水域和非定常计算的边界元方法。它是通过使用离散尾流片的涡格提升线法进行全尾流对齐的方式来实现的。描述了将提升线的尾流片转换为边界元法的尾流片的技术。然后对开阔水域和非定常情况进行数值模拟。它表明耦合方法预测的结果与边界元方法相似，特别是对于开阔水域的情况。还观察到计算时间的明显减少，对于开放水域和非定常计算分别为 70% 和 65%。
