| Abstract: | This paper has modified the model of evaporating process at constant heat flux boundary condition,which introducing the working fluid＇s pressure drop and physical parameters.Numeric method has been applied to computing the evaporating process of R407C,which gives the distribution of pressure,temperature,vapor quality and temperature difference between working fluid and heat exchanging fluid.At last the outputs of the modified model and the original model has been compared. |
