Evaporation in Porous Media with Large Evaporation Rates

Application ID: 33731

Evaporation in porous media is an important process in the food and paper industries, among others. Many physical effects must be considered: fluid flow, heat transfer, and transport of participating fluids and gases. All of these effects are strongly coupled and predefined interfaces can be used to model these effects with the Heat Transfer Module.

This tutorial model describes an arbitrary case of drying a wet porous object using laminar air flow. The air is dehumidified at the inlet to the porous object where its moisture content increases as it flows through the porous medium. The model focuses on the steps required to implement simulate multiphase flow in porous media, in the Heat Transfer Module, together with the evaporation of the liquid to a gaseous phase. Water saturation in the porous medium is computed over time.

This model example illustrates applications of this type that would nominally be built using the following products:
