International audience; Two preliminary experiments show that a non-equilibrium situation can be easily encountered during a natural drying process. This leads us to reconsider the thermodynamic local equilibrium assumption, and propose a macroscopic

A theoretical and experimental analysis of the phase change of a volatile liquid in an unsaturated soil is presented. Expression of the rate of phase change of the pore liquid is developed within the framework of nonequilibrium thermodynamics. An exp

This anick concerns the convective drying of natural rubber in granule form and aims at improving production. Parts of the research have already been published. With a validated mathematical model, il is possible to know the properties of the medium

A model taking into account the simultaneous influence of mechanical and hygrometric actions (Mrani and al., 1995a, 1995b) was applied to study of the dehydration of a cylinder of highly deformable biphase gel (agar gel) (Mrani and al., 1995b). Numer

A phenomenological equation is established for water transport in a biconstituent, isotropic, isothermal elastic medium. The equation includes a term related to the water content gradient and a term related to the deformation gradient. It is shown th

Cette etude aborde la mesure des proprietes d'un biopolymere, le gel d'agar, au cours d'un processus de deshydratation. La morphologie du gel est mise en evidence par des observations au microscope electronique en utilisant une technique de cryofract

An analysis of convective drying of natural rubber in granule form. Exploitation of the mathematical model developed from analysis of internal transfers requires determination of the ‘drying rate’ and the ‘energy exchange coefficient’ between

The mathematical model proposed enables the description of mass and energy transfers during convection drying of granular materials. It shows evolution of the water content of the material in time and space, air and grain temperature, relative humidi
