建立了液滴散热器中工作流体的循环模型。该模型基于伯努利定律和水头损失。在改变循环工质流量的情况下，用该模型计算的工质循环特性与实验结果进行了比较。在散热器中，为了配合大空间结构中产生的余热的变化，改变循环工质的流速。该模型计算的循环工质流量与实验结果吻合较好。阐明了液滴散热器中工质的循环机理。本文所建立的模型将使我们能够自动控制液滴散热器中工作流体的流量。
A model of the circulation of the working fluid in a liquid droplet radiator has been developed. The model is based on Bernoulli's law and the loss of the hydraulic head. The behavior of the circulation of the working fluid calculated from the model is compared with that obtained from experiments in the case that the flow rate of the circulating working fluid is changed. In radiators, the flow rate of the circulating working fluid is changed in order to match the change of the waste heat generated in large-space structures. The flow rates of the circulating working fluid calculated from the model correspond to those obtained from the experiments well. The circulation mechanism of the working fluid in the liquid droplet radiator has been clarified. The model developed in the present work will allow us to control the flow rate of the working fluid in the liquid droplet radiator automatically.
