Resolution by the Finite Elements of the Equations of Couples Transfers Masses and Energy in a Porous Wood Environment: Case of the Drying of the Iroko

Abstract: In this work, we discuss the transfer phenomena in porous media, applied in a hygroscopic material during drying. The study is undertaken within the framework of initiation to research in master. The coupled equations of heat transfer and mass are written from the Luikov model to which the simplifying assumptions are associated. The space-time equations are solved in 2D by the finite element method, before determination of the average sizes of moisture and temperature for comparison with the experimental results. It is a pattern of behavior contributing to the control of the process to predict possible cases of simulation of influence of drying parameters. The material chosen is the Cameroon Iroko (Chlorofora exelsa) which is a large forest product use for the manufacture of internal or external furniture. Drying is done in an insulated enclosure calm atmosphere. Thermophysical and hygroscopic properties necessary for solving the equations are derived from the literature and previous works. The analysis of theoretical and experimental results leads to an average relative error of 3.238 % for different temperatures applied.
