| 摘 要： | 本文通过振荡流热管可视化实验，研究热管传热性能与流型的变化。实验中可观察到，振荡热管内工质运动通常处于“间歇-振荡”交替运行的状态。随加热功率的增大，间歇时间所占比例逐步减小。随着加热功率的增大，热管内的流型也发生相应变化，实验中主要观察到了泡状流、塞状流、环状流、局部波状流等多种流型。汽泡的生成、长大、聚合、分离和湮...

| Abstract: | Visualization experiments were performed to observe the thermo-hydrodynamic regimes of the oscillating heat pipe.Alternate oscillation and stagnation motions of the working fluid can be seen from the experiment,the higher heating power the shorter interval time of the oscillating motion.The flow pattern varied with change of heating power.The bubbly flow,slug flow,annular flow and local wave flow appeared in different stages.The inception,growth,combination,separation and collapse of the bubbles in the heat... |
