| Abstract: | In this paper,the heat transfer performance of the umbrella-plate falling film evaporator was studied with water and 5%~40% potassium carbonate solutions being used as medium.The influence factors of the heat transfer performance and the formula of the heat transfer coefficient on the evaporation side in the umbrella-plate have been obtained.By experimental investigation to the break of liquid film,we proved that the relational expression between non-dimensional heat flux B and critical Reynolds number. |
