An Analytical-Numerical Method for Simulating Water Transfer in a Ventilated Deep Bed of Cereals

This is the authors' abstract. We don't add key points for this paper.

WHEAT drying and wetting in a ventilated deep bed are simulated according to a mixed methodology combining the analytical solution of the mass transfer equation and a numerical iteration procedure. The analytical solution implies the knowledge of the mass transfer coefficient determined experimentally. Through dimensional analysis the transfer coefficient is related to grain and air characteristics. A practical result of the simulation is the establish-ment of a multi-entry diagram which can be of direct help in wheat drying.
