In a falling-film evaporator, feed enters from the top of the evaporator. It then flows down the inside walls of the tubes as a thin film. As the feed travels down the tube, evaporation occurs. The vapor/liquid mixture travels down the remaining tube length and into the vapor head. The vapor is removed through the top of the vapor head, while ...

Falling Film Tubular Evaporator Thermal Kinetics

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. In the head, the product is evenly distributed into the heating tubes. The liquid enters the heating tube and forms a thin film on the tube wall where it flows downwards at boiling temperature and is partially evaporated.

Development of Falling Film Heat Transfer Coefficient for ...

In falling film evaporators, the overall heat transfer coefficient is controlled by film thickness, velocity, liquid properties and the temperature differential across the film layer.
