Mathematical modeling of the diffusion of liquids in the gaseous phase by evaporation

Abstract

The objective of this study is to analyze the behavior of liquid molecules during an evaporation process, a mathematical model is proposed through mass a balance that describes said behavior under steady-state conditions and the variation in composition is analyzed in detail, through a finite space. In order to know the concentration profile, it is necessary to characterize the behavior of the moisture present in the medium as part of the parameters that affect the system, which will at the same time allow knowing the molar composition of the water present in the medium or system of study. Temperature is another of the variables of great importance in the evaporation process, which is why a variation of the concentration profile will occur at different temperatures.
