steady flow in pipe network 管网恒定流
steady turbulent flow in pipe 圆管内定型湍流
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。
Calculation showed that when the heat flow is in steady state, temperature-increasing difference in inner, outer pipe walls bearable for partial corrosive pipeline represents a minimum value.
计算表明,当热流处于稳定状态时,局部腐蚀管道所能承受的内、外壁增温差为最小值。
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。
