不凝性 meaning in Chinese
incoagulabilily
Examples
- Condensation of steam in the presence of noncondensable gases is an important heat transfer mode in the passive containment cooling system ( pccs ) . in the past decade , great efforts have been made on the investigation of this regime
含有不凝性气体的蒸汽冷凝是先进反应堆非能动安全壳冷却系统( pccs )中重要的换热方式，是当前核反应堆热工水力学研究的一个热点。 - The condensation heat - exchange characteristic of a separate - type heat - pipe was studied on a 1 : 1 model . the heat pipe is heated by electricity , and working fluid is distilled water , and it is cooled by air . the experimental results show that , ( 1 ) when charging liquid ratio is 45 % , condensation heat - exchange coefficient reaches to maxium ; ( 2 ) when there is not non - condensing gas , the coeffcient decreases a little with the increase of vapour pressure , and it decreases by 9 . 5 % when the pressure increases from 0 . 16mpa to 0 . 36mpa ; ( 3 ) when there is non - condensing gas , the coefficient decreases a little , but when the gas is discharged by an exhaust value , it can be improved , when the volume content of the gas is 2 . 5 % , it can increased by 22 % ; ( 4 ) the effect of the non - condensing gas on the coefficient decreases with the increase of the pressure , and when the volume content of the gas is 5 % and the pressure increases from 0 . 16mpa to 0 . 36mpa , the coefficient increases by 6 % . the relative curves are given between condensation heat - exchange coefficient and air flowrate , charging liquid ratio and vapour pressure
建立了空气冷却实验台，热管的加热方式为电加热，工质为蒸馏水.在1 1模型上对分离式热管管内凝结换热特性、不凝性气体对凝结换热的影响及不凝性气体的扩散规律进行了试验，得出分离式热管有一最佳充液率，其值为45 %左右；凝结换热系数随着蒸汽压力的增加略有降低，在实验的压力范围内，降低了9 . 5 % ；不凝性气体对分离式热管的凝结换热仅影响冷凝段下部较小部分，通过排气阀排出不凝性气体可有效地改善冷凝段下部的凝结换热；随着压力的增加，不凝性气体对分离式热管冷凝段的影响减少.这些结论可用于分离式热管换热器的工程设计和控制 - Abstract : the condensation heat - exchange characteristic of a separate - type heat - pipe was studied on a 1 : 1 model . the heat pipe is heated by electricity , and working fluid is distilled water , and it is cooled by air . the experimental results show that , ( 1 ) when charging liquid ratio is 45 % , condensation heat - exchange coefficient reaches to maxium ; ( 2 ) when there is not non - condensing gas , the coeffcient decreases a little with the increase of vapour pressure , and it decreases by 9 . 5 % when the pressure increases from 0 . 16mpa to 0 . 36mpa ; ( 3 ) when there is non - condensing gas , the coefficient decreases a little , but when the gas is discharged by an exhaust value , it can be improved , when the volume content of the gas is 2 . 5 % , it can increased by 22 % ; ( 4 ) the effect of the non - condensing gas on the coefficient decreases with the increase of the pressure , and when the volume content of the gas is 5 % and the pressure increases from 0 . 16mpa to 0 . 36mpa , the coefficient increases by 6 % . the relative curves are given between condensation heat - exchange coefficient and air flowrate , charging liquid ratio and vapour pressure
