摘要
对摇摆条件下的单相强迫循环流量脉动特性进行实验研究,并通过受力分析研究影响流量脉动的主要因素。研究表明:摇摆运动能否造成强迫循环流量出现周期性的脉动主要取决于泵驱动压头与附加惯性力的相对大小。摇摆幅度或频率越大,流量脉动幅度越大;循环泵驱动压头越大,流量脉动幅度越小;当驱动压头与附加惯性力的比值达到一定值后,摇摆运动发生前后流量不再出现明显变化。
The characteristics of single-phase flow rate pulsation under rolling motion condition are experimentally studied, and the main factors having effects on the flow rate pulsation are also studied based on the force analyze. The results show that the flow rate pulsation depends on the relative magnitude of drive force and additional inertia force. Larger rolling amplitude or frequency will result in more violent flow pulsation. However, the amplitude of flow rate pulsation decreases with the increasing of drive force. And the flow rate does not present significantly variation before and after rolling motion start as the ratio of drive force to additional inertial force large enough.
