雷诺数范围 meaning in Chinese
reynolds number range
Examples
- So people are interested in the using of twisted - tape insert . a large number of researches on twisted - tape have been reported in the literature . but most of the researches were conducted with turbulent flows or laminar flows
迄今为止，关于扭带强化传热的研究已经取得不少成果，但这些成果或是在较高的雷诺数范围或是在较低的雷诺数范围获得的，应用条件有明显的局限性。 - In accordance with different tripping annulus at the inlet , the numerical simulations of the reattachment length were performed with the " variable c ? " model . in the range of experimental reynolds number , the tripping effect on the reattachment length was developed in the figure . the dependence of the reattachment length on reynolds number was also analysed in the different status of pipe flow
利用变模型常数的-模型针对不同尺寸的挡环进行了再附着长度的模拟计算，在实验雷诺数范围内，建立了入口处挡环对再附着长度影响的变化曲线，分析了再附着长度在不同的管流流动状态下相对于雷诺数的变化情况。 - The experimental model is a rectangular section of 15 . 2 187mm ~ 2 , which is composed of two aluminum plates . the angles between the internal netted rib turbulators and the flow direction are 45 ? for the one plate and 60 ? for the other , or both 45 ? for two plates . in the experiment , the re numbers changes from 0 . 4 10 ~ 4 1 . 5 10 ~ 5 , rib width - to - pitch are 0 . 25 , 0 . 3 and 0 . 5 , rib width - to - height are 0 . 25 , 0 . 3 and 0 . 5 , the rib height - to - hydraulic diameter ratio is 0 . 246
