为了研究在摇摆工况下船舶流体系统的流量波动特性，建立摇摆实验平台模拟海洋环境，进行窄矩形通道内流量波动特性研究。结果表明，由摇摆运动引起的附加力会使流体系统的流量发生周期性的波动，且波动周期一致。附加切向压降和附加向心压降的波动振幅随着摇摆角度和摇摆频率的增加而迅速增加，然而时均质量流量随着摇摆角度和摇摆频率的增加减小。在摇摆工况下流量的相对波动振幅随着摇摆角度和频率的增加而增加，随着雷诺数的增加而减小。
In order to investigate the flow rate fluctuation characteristics of the ship fluid system under rolling motion, a rolling experimental platform was established to simulate the ocean conditions, and the flow fluctuation characteristics in a rectangular narrow channel was studied. The results demonstrate that the fluid will be effect by the additional inertia forces under rolling motion, the flow rate will fluctuate periodically, and the fluctuation period is same with the rolling period. The fluctuation amplitudes of additional tangential pressure drop and additional radial pressure drop will increase rapidly with the increase of rolling angle and rolling frequency, but the mass flow rate will decrease with increasing rolling amplitude and frequency. The relative pulsation amplitude of mass flow rate will increase with the increase of rolling amplitude and rolling frequency, while decreasing with the increase of Reynolds number.
