Thin-liquid-film evaporation at contact line
WebIn order to reduce the evaporation temperature at the heated evaporation surface as far as possible the pressure incl. the hydrostatic pressure due to the liquid product itself should be minimized. The solution is a thin film of the liquid product on the inner side of a vertical evaporation pipe which is generated by a rotating wiper system. WebApr 11, 2024 · The evaporation is in turn determined by heat conduction across the liquid film, kinetic resistance, and the Kelvin effect (i.e., saturation-condition dependence on the liquid-vapor pressure ...
