帶窄縫多箱體系統(tǒng)波浪荷載特性分析
[Abstract]:In order to solve the problem of fluid resonance caused by the interaction between wave and multi-fixed right angle box structure with narrow slot, a two-dimensional time-domain model for nonlinear wave load analysis is established. In this model, the incident waves are generated by the technique of intra-domain wave generation, and the free water surface satisfies the fully nonlinear kinematic and dynamic boundary conditions, and the free water surface in the narrow slot is equivalent to viscous dissipation caused by vortex motion and flow separation by introducing artificial damping into the free water surface. The boundary integral equation is established and the unknown quantities such as velocity potential on the surface are solved by means of high order boundary element discretization, and then the time derivative of velocity potential is obtained by using the method of acceleration potential. Based on the Bernoulli equation, the instantaneous wave loads on the structure are obtained. The accuracy of the model is verified by simulating the horizontal force and vertical force of the three-box body with two narrow slots and comparing with the published results. At the same time, through a large number of numerical calculations, the influence of the number of boxes on the magnitude and variation of wave loads on each box is analyzed.
