In this paper, the heat dissipation structure of separated heat pipe is designed and studied. Firstly, based on Newton's heat transfer law in problem 1, the calculation method of convective heat transfer coefficient is obtained by differential solution. The coefficient effectively reflects the convect...
19.If the convective heat transfer coefficient is great enough, its rechange has smaller effect on temperature response. 当对流换热系数足够大时,再改变对流换热系数对温度影响较小。 20.An optical flow method instead of the cross correlation method is proposed for convective precipitation system. ...
英语翻译 Choi et al.investigated the convective boiling heat transfer coefficient of R-22,R-134a,and CO2 in horizontal minichannels with inner diameters of 1.5 and 3.0 mm constructed of stainless steel tube and a length of 2 m.They found that the average heat transfer coefficient ratio of R-...
Furthermore, convective heat transfer coefficient, heat exchanger effectiveness, pressure drop, friction factor, under different conditions, are measured. The results demonstrate convective heat transfer coefficient of U-bend double pipe heat exchangers is enhanced by 35% for 1 MgO vol.% and 0.2 Cmc...
Convective effects and, consequently, the heat transfer coefficient are enhanced by increasing the two-phase velocity as results of augmenting the vapor specific volume, due to the saturation temperature decreasing. From: Microchannel Phase Change Transport Phenomena, 2016 ...
Comparisons of the thermal insulation, the inner flow pattern and the heat transfer between the two sandwich panels are completed subsequently according to the results from forced convective experiments and numerical simulation. Within the Reynolds number range of interest for this study, the Kagome ...
The experimental setup consists of a steel specimen of a representative size and geometry (helical springs and straight wires) subjected to an air cross-flow in a wind tunnel. Joule heating is applied to the specimen, and the effective heat transfer coefficient is calculated from the input ...
