The theoretical model was established to describe steady state circulation flow of a single loop pulsating heat pipe(PHP)with thermo-mechanical and hydrodynamics analysis.
分析显示，稳定循环时，系统循环体积功用于克服系统循环耗散功，而系统循环耗散功（热）与热管传热量呈一定关系。
The traditional quasi-steady friction models are proved to be inaccurate in transient pipe flow because they underestimate friction losses in transients.
在液体管道瞬变流计算中，传统的拟恒定摩阻模型不能准确描述瞬变流的真实物理现象。
The traditional quasi - steady friction model can not be accurately described the real transient problems in transient pipe flow.
