【Abstract】 Under the state of surface evaporation, the experimental study of the falling film breakdown have been done down the vertical dimpled plate with 2 m long and 0.5 m wide. Falling film breakdown can be divided into temporary breakdown and permanent breakdown. The two main parameters relating to the falling film breakdown were critical heat flax and minimum flowrate per unit plate width. The correlations of critical heat flux and criterion for falling film breakdown were obtained to predict the falling film breakdown down vertical dimpled plate.更多还原
