水平管外降膜蒸发传热性能的实验研究

An Experimental Study on the Heat Transfer Performance of the Falling Film Evaporators Outside Horizontal Tubes

以水为介质研究了水平管外降膜蒸发的传热性能,并对喷淋密度和热通量等因素对传热性能的影响进行了分析,得到了传热系数关联式,该式的计算值与实验值相差在±10%以内。

The heat transfer performance of the falling film evaporators outside horizontal tubes was studied with water as a medium, the influences of the sprinkling density and heat flux on the heat transfer performance of the evaporators were analyzed and studied, the correlative formula of the heat transfer coefficient was obtained, the error between the calculated value of the formula and the experimental value was within ±10%.
