摘要
深海网架式模块化渔场是一种新型的海上渔场养殖平台,网箱浮架结构在海浪中的波浪载荷是该平台设计研究中的关键环节.在应用Morison方程计算网箱浮架结构的波浪载荷时,浮架中的球体与管结构的连接形式会对周围的流场产生影响,而且Morison方程中水动力系数的选取在考虑粘性影响方面存在不确定性.论文尝试应用CFD方法计算球管结构水动力系数,并通过Morison方程对网架式网箱浮架结构的波浪载荷进行计算分析,然后将它与CFD数值模拟得到的浮架结构波浪载荷计算结果进行比较.研究表明,采用CFD与Morison方程结合的方法能够较好地计算网箱浮架结构的波浪载荷.
Deep-sea grid modular fishery is a new type of offshore aquaculture platform.When the Morison equation is used to calculate the wave load on the grid cage,the connection form of the sphere and the pipe structure in the cage frame will affect the surrounding flow field,and the hydrodynamic coefficient used in the Morison equation is not accurate enough when considering the viscous effect.This paper combines the CFD method and the Morison equation to calculate wave load of the grid cage,and the result is compared with that of the CFD method.It is concluded that the present method is reasonable and feasible for calculating wave load on the grid cage.
