![عکس صفحه اول مقاله: Electrolyte film evaporation under the effect of externally applied electric field Electrolyte film evaporation under the effect of externally applied electric field](/preview/png/668567.png)
The effect of an externally applied electric field and bulk ion-concentration on the evaporation rate of an electrolyte film in contact with a wall is studied numerically. A mathematical model for steady state condition is developed to couple momentum, energy, and mass conservation equations together with the Poisson–Boltzmann equation that describes charge distribution in the liquid film. The model also describes the interaction with humid air flowing above the electrolyte film. The results show a non-uniform volumetric heat generation due to Joule heating that induces a temperature variation along the film length and in the direction away from the wall.
► We model the effect of an external electric field on the evaporation of an electrolyte film.
► The model also describes the interaction with humid air flowing above the film.
► Coupled momentum, energy, and mass conservation are solved together with the Poisson–Boltzmann equation.
► Non-uniform heat generation inside the film is obtained.
► Electric field affects the hydrodynamics inside the liquid film and ion concentration affects the temperature distribution.
