给出了水平铜镍海水淡化管外表面薄海水膜的蒸发换热系数。测试是使用1.0英寸和2.0英寸进行的。直径的电加热光滑管，以及2.0英寸。直径电加热滚花管。获得了从120到260华氏度的饱和温度范围内的传热数据，给水流量高达1105 LBM/小时英尺管长，热通量高达20,000 Btu/小时英尺2。观察到胶片有一些沸腾。给出了蒸发过程的实验换热系数，并对其进行了讨论，并与以前报道的数据进行了比较。
Evaporation heat transfer coefficients are presented for thin sea water films flowing over the outside of horizontal copper-nickel desalination tubes. Tests were conducted using both 1.0-and 2.0-in. diameter electrically heated smooth tubes, as well as a 2.0-in. diameter electrically heated knurled tube. Heat transfer data were obtained for saturation temperatures ranging from 120 to 260 F, with feedwater flow rates up to 1105 lbm/hr-ft of tube length and heat fluxes up to 20,000 Btu/hr ft2. Some boilingof the film was observed. The experimental heat transfer coefficients for the evaporation process are presented, discussed, and compared with previously reported data.
