Numerical analysis of the diffusion equation for composite solids: Application to grain drying

The drying of a hydroscopic porous solid consisting of two concentric spheres was simulated by means of Fick's second law of diffusion. The resulting mathematical equation and boundary conditions were numerically solved and the numerical solution was used to simulate the drying of two concentri...

description The drying of a hydroscopic porous solid consisting of two concentric spheres was simulated by means of Fick's second law of diffusion. The resulting mathematical equation and boundary conditions were numerically solved and the numerical solution was used to simulate the drying of two concentric spheres with different shell thicknesses and relative resistances to moisture flow. The model was used to simulate the drying process of corn. From the comparison between theoretically predicted and observed drying curves it was found that the kernel-to-pericarp diffusivities ratio is about 0·1. © 1992.
