摘要:
为了研究位置分布复杂的多体浮动平台的水动力相互作用规律,利用三维势流理论和Green函数法,提出了同时考虑浮式单元(浮体)相对方位与浮体间距影响的计算模型。通过建立流场势流问题的定解条件,求解流场总速度势。使用面元法离散网格,通过数值计算得到了任意浮体所受流场的总作用力。提出了一种简化模型,分析得到了水动力系数受夹角与间距共同作用影响的规律。当浮体间距较小时,夹角对水动力系数影响较大,且存在一个最佳角度; 当间距较大时,夹角对水动力系数影响不显著,而间距受波浪的相位关系影响较大。
Abstract:
In order to research the law of hydrodynamic interaction between floating units in multi-body floating systems,a calculation model considering the influences of gaps and the relative orientation of floating units simultaneously is proposed by using the three-dimension(3D)potential flow theory and the Green's function method.The definite conditions of the potential flow problem of flow fields are established,and the total velocity potentials are calculated.The surface panel method is introduced to discrete grids,and the resultant force on any floating body from flow field is obtained by numerical calculation.A simplified model is proposed,and the law of hydrodynamic coefficients affected by angles and gaps is obtained.When the floating unit's gap is small,the angle makes great influence on hydrodynamic coefficients,besides there is an optimum angle.As the floating unit's gap is large,the influence made by the angle on the hydrodynamic coefficients is not significant any more,while the phase relationship of the gap and wave appears remarkable.
