Falling Film Evaporation - an overview

Falling Film Evaporation - an overview

Falling film evaporation on the horizontal tube is a new technology for seawater desalination. Because the phase changes occur on both sides of film evaporation and the film flow of the liquid outside the tube contributes to speed up the separation of vapor and liquid, its heat transfer coefficient is high.
