中文摘要：基于黏性流理论,采用有限体积法,考虑多种波浪参数和截面形状,计算淹没水平柱体在波浪作用下的受力.通过受力分解和局部流场特征分析,探究了波浪参数和截面形状对柱体受力的影响.结果表明,3种不同截面形状柱体受力主要由惯性力主导,柱体的淹没体积更大程度地决定了柱体所受波浪力的大小.在相同宽高比条件下,矩形柱淹没体积最大,其次是曲边矩形柱,最小的是椭圆柱.因此,综合考虑3种截面形状淹没水平柱体,矩形柱所受波浪力最大,椭圆柱所受波浪力最小,且随着宽高比的增大逐渐减小.

外文摘要：Based on the viscous flow theory,employing the finite volume method,considering variety of wave parameters and cross-section shapes,the forces on the submerged horizontal cylinder under waves are calculated.Through the force decomposition and the feature analysis of local flow field,the influences of wave parameters and cross-section shapes to forces on the cylinder are explored.The results show that the forces on cylinders with three different cross-section shapes are mainly dominated by the inertial forces.The magnitude of the wave forces on the cylinder is more determined by the submerged volume of the cylinder.Under the same aspect ratio,the submerged volume of the rectangular cylinder is the largest,the second is the curved rectangular cylinder,and the smallest is the elliptical cylinder.Therefore,comprehensively considering the three cross-section shapes of the submerged horizontal cylinder,the wave forces on the rectangular cylinder are the largest,and the wave forces on elliptical cylinder are the smallest.The wave force gradually decreases with the increase of the aspect ratio.
