提出了一种改进的常数面元法，以更精确地计算波浪漂移力和力矩。采用求解边界积分方程的边界元法计算浮体的速度势。用高阶边界元法或常数面元法离散方程。用常数面元法计算速度势虽然简单，但不能准确计算波浪漂移力和漂移力矩。本文提出了一种改进的常数面元法来解决这些问题。改进的常数面元法可以很容易地应用近场法计算波浪漂移力和力矩，特别是对于多浮体的情况。将新的评价方法的结果与其他评价方法进行比较。此外，将评估多个浮体之间的流体动力相互作用。
An improved constant panel method for more accurate evaluation of wave drift forces and moment is proposed. The boundary element method (BEM) of solving boundary integral equations is used to calculate velocity potentials of floating bodies. The equations are discretized by either the higher-order boundary element method or the constant panel method. Though calculating the velocity potential via the constant panel method is simple, the results are unable to accurately evaluate wave drift forces and moment. An improved constant panel method is introduced to address these issues. The improved constant panel method can, without difficulty, employ the near-field method to evaluate wave drift forces and moment, especially for multiple floating bodies. Results of the new evaluation method will be compared with other evaluation method. Additionally, hydrodynamic interaction between multiple floating bodies will be assessed.
