Based on the PoissonBoltzmann equation for electric double layer and NavierStokes equation for the flow of liquid

a mathematical model to simulate the complex coupled heat and moisture transfer in porous fibrous media with consideration of the effects of electric double layer is presented. With specification of initial and boundary conditions

the distributions of the temperature and liquid water content in the porous fibrous media were numerically computed. The comparison with a series of experimental measurements

which shows the superiority of this model in resolving the coupled heat and liquid moisture transfer in porous fibrous media

illustrates that the heat and moisture transfer process is influenced by the electric double layer.
