一种新的理性理论预测了舷侧干涉对船舶在平行航道中波浪前进的水动力的影响。辐射问题是通过扩展纽曼统一理论的正向速度版本来解决的。哈斯金德-纽曼互易关系给出了波激力和波激运动。能量守恒给出了与远场辐射波相关的Kochin函数的阻尼系数公式。通过实验和简单体三维面板法的独立数值解验证了该理论。提供了新的检查侧壁干涉的图表。
A new rational theory predicts the effects of side-wall interference upon the hydrodynamic forces on a ship advancing in waves generated in a parallel-sided waterway. The radiation problem is solved by extending the forward-speed version of Newman's unified theory. Haskind-Newman's reciprocity relation gives wave-exciting forces and motions. Energy conservation gives a formula for the damping coefficients from the Kochin function associated with the far-field radiated waves. The theory is validated by experiments and independent numerical solutions by a 3-D panel method for simple bodies. New diagrams for checking the side-wall interference are provided.
