Falling film evaporator (FFE) - Fabex Engineering

Falling Film Evaporators (FFE) are one of the most popular evaporators used due to simplicity of operation, low temperature difference and high heat transfer coefficients. In FFE, the liquid enters the top of the Shell and Tube Heat Exchanger and vapours are generated in the heating tubes. The liquid and vapours both flow co-currently in ...

Numerical Simulation for Falling Film Thickness around Horizontal Tube ...

Falling film on horizontal tube evaporators, of both Mechanical Vapor Compression (MVC) and the Multi-Effect Distillation (MED) desalination systems, plays an important role in the heat and mass transfer (evaporation) and accordingly the systems productivity. Falling film thickness is mainly influenced by the intertube space, circumferential angle and the film’s Reynolds number.

Falling film heat transfer analysis on a bank of horizontal tube evaporator

Falling film heat transfer analysis on a bank of horizontal tube evaporator

Heat transfer analysis of falling film evaporation on a bank of horizontal tubes is investigated in this study. Liquid falling from one tube to the next lower one is considered as a thin liquid jet impinging on the top of the tube with a uniform free falling velocity. The hydrodynamic and thermal solutions are obtained by a finite difference ...

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. ... There are also applications where the process fluid evaporates on the outside of horizontal or vertical tubes. In all cases, the process fluid to be evaporated flows downwards by gravity as a continuous film.
