The Efect of Pressure in 2D Luikov Drying Problem.

Abstract

Multidimensional drying in capillary porousm media is analytically solved for the associated temperature, moisture and pressure content distributions. Luikov's model with linear transport coefficients and two-dimensional plate geometry is adopted for description of the simultaneous heat, mass and pressure transfer phenomenal. The generalized integral transform technique (G.LT.T.) is applied to the problem and the automatically global error-controlled solution of the coupled partial differentiale quationsis used to achieve the solutions. The convergence behavior of the proposed eigenfunction expansions is illustrated.
