An Experimental Investigation of Heat Transfer in Forced-Convection Evaporation of Oil-Refrigerant Mixtures 油-制冷剂混合物强制对流蒸发传热的实验研究
对油-制冷剂(R-12)混合物在水平管内的强制对流蒸发进行了两相局部传热测量,实验参数包括0%、2%和5%的油质量流量;热力学性质范围。002比1;热通量范围为700至20000 Btu/h•ft²(2.2X10³至6.3x104W/m²);蒸发压力为43至65 psia(.29至0.25 MPa);质量流量范围为7x104t至5X105lbm/h•ft2(3.4x105kg/h至2.4X106kg/h m²)。建立了一个关联式,预测在整个范围内86%的传热误差在±35%以内。还介绍并讨论了蒸发的流程图。单位:双引文:ASHRAE交易,1986年,第卷。 第92页。2A,波特兰,或
Two-phase local heat transfer measurements are made for forced-convective evaporation of oil-refrigerant (R-12) mixtures inside a horizontal tube, The experimental parameters cover the range of 0%, 2%, and 5% oil by mass flow; thermodynamic quality range of.002 to 1; heat flux range of 700 to 20,000 Btu/h•ft2(2.2X103to 6.3x104W/m2); evaporating pressures from 43 to 65 psia (.29 to.25 MPa); and mass flux range of 7X104to 5X105lbm/h•ft2 (3.4x105to 2.4X106kg/hr m2). A correlation is developed that predicts 86% of the heat transfer within an error of ±35% over this entire range. Flow maps for evaporation are also presented and discussed.Units: Dual
