摘要
在间隙为1.5mm的垂直环形窄缝通道内,通过内外管双面通电来加热流体,进行环形窄缝内单相液体传热和压降的研究。通过实验得出,内管和外管的Nu数准则式,双面加热时,内管对外管、外管对内管传热的影响,单相压降计算公式以及传热和流动的联系。
Experiments were conducted to study the single-phase forced convection heat transfer and flow in vertical 1.5mm annuli. The test section can be simultaneously heated from inner and outer tubes by electricity. Based on these data, the Nu number and the friction factor correlations were obtained. A comparative analysis on heat transfer between bilateral and unilateral heating was carried out. At last, the analogy of momentum and heat transfer was carried out.
