摘要
在间隙为1.1和1.6 mm的环形窄缝通道内,通过内外管双面通电加热流体,进行环形窄缝通道内的干涸后弥散流区压强的试验研究,通过试验得出环形窄缝通道内干涸后弥散流区全汽相摩擦倍增因子的计算式,该式能够较好地预测环形窄缝通道内干涸后弥散流区的两相摩擦压降。
Experimental study associated with post dry-out mist flow in the vertical narrow annuli with the gap width of 1.1 and 1.6 mm was conducted. The test section can be simultaneously heated from inner and outer tubes by electricity. Based on experimental data, a new correlation of two-phase multiplier, which was based on single steam phase flow in the ducts, was developed. The new correlation can predict the experimental data well.
