HEAT AND MASS DIFFUSION AND SHRINKAGE IN PROLATE SPHEROIDAL BODIES BASED ON NON-EQUILIBRIUM THERMODYNAMICS: A NUMERICAL INVESTIGATION

RESUMO
The diffusion phenomenon exists in many industrial applications such as in the drying, wetting, heating, and cooling of solids, and principally in biological products such as in foodstuffs (grains, fruits, vegetables, etc.). In this sense, a new mathematical formulation to describe the simultaneous heat and mass (liquid and vapor) transfer and shrinkage during drying of capillary-porous bodies, with particular reference to prolate spheroid solids, is presented. The mathematical model was based on non-equilibrium thermodynamics considering variable transport coefficients and convective boundary conditions at the surface of the solid, including dimension variations. All of the governing equations presented in the model are written in prolate spheroidal coordinates and solved numerically by the finite-volume method using fully implicit formulation. An application of the methodology was used to predict drying of wheat kernel. Results on drying and heating kinetics, and on the moisture content and temperature distributions in a wheat kernel during the drying process, are presented and analyzed. The methodology also allows verification of heat, liquid, and vapor fluxes, taking into account the thermal and moisture gradients inside the grain.
