摘要: 从流体基本控制方程出发,分析海洋条件对强迫循环流动特性的影响;并采用CFD方法进行模拟及验证。计算发现,在流速一定的条件下,重力、向心力和角加速惯性力等与流体流动无关的惯性力的引入对流型和摩阻没有明显影响;而由于旋转效应引起的科里奥利力会对流型产生影响,在角速度很大的情况下,会对摩阻产生一定影响。

Abstract: Based on the basic governing equations,the effect of the ocean conditions on the flow characteristics of the forced circulation is analyzed,and is simulated and verified by CFD calculation method.The calculation results showed that under a given velocity,the gravitational force,centripetal force and angular acceleration force caused little effect on the flow configuration and frictional resistance.But the Coriolis force caused by rolling effect,can influence the flow configuration,and with the larger palstance,it will influence the frictional resistance.
