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

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%.
