| Abstract: | The heat transfer characteristics of a dimply-shaped vertical plate falling film evaporator was studied,the heat transfer on the inside and outside sides of the vertical plate in different flow conditions of liquid film was also studied,the relation of the branch coefficient of the dimensionless heat transfer was derived,it was concluded that the emphasis must be put on the evaporating side of the evaporator for improving heat transfer characteristics. |
