Secagem de sólidos esferoidais usando o método de Galerkin.

Abstract

An analytical solution of the transient diffusion equation based on the liquid diffusion theory to describe mass transfer inside the spheroids by considering constants diffusion coefficient and equilibrium boundary condition at the surface of the solid is presented. The diffusion equation in the cylindrical coordinates system applied for two-dimensional case was solved using the Galerkin Method. Results of the moisture content distribution and average moisture content during drying process to many spheroids are presented and analyzed.
