    Abstract The influence of air temperature on drying kinetics of radish slices in a bench scale convective tray dryer was examined experimentally and suitable drying model was developed. The experiments of drying of radish slices were conducted at 40, 50 and 60 °C with an air velocity of 2 More >

    A Comparative Study of Different Drying Processes for a Deformable Saturated Porous Medium

    Nour El Houda Ben Mustaphaa1,3,*, Ibtissem Boumnijel1, M. El-Ganaoui2, Daoued Mihoubi1

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.6, pp. 1339-1348, 2023, DOI:10.32604/fdmp.2023.022888

    Abstract Drying of a deformable saturated porous medium based on convective tempering is a novel method that can enhance energy efficiency and the quality of the dried product itself. In this experimental investigation, the performances of this specific technique are compared with those of a standard stationary drying process in terms of deformation, drying kinetics, moisture redistribution, and energy consumption. In particular, the response of a deformable saturated porous medium (Kaolin) is considered. The results are critically discussed pointing out advantages and drawbacks. More > Graphic Abstract

    M. Toujani1, R. Djebali2, L. Hassini1, S. Azzouz1, A. Belghith1

    CMES-Computer Modeling in Engineering & Sciences, Vol.98, No.5, pp. 469-485, 2014, DOI:10.3970/cmes.2014.098.469

    Abstract In the present work we aim to simulate unsteady two-dimensional evolution of the moisture content, temperature and mechanical stress in a parallelepiped apple sample during convective drying. The model is based on the heat and mass transfer equations and the mechanical equilibrium equation under the assumptions of plane deformation, viscoelasticity and isotropic hydric shrinkage. The Finite Elements COMSOL Multiphysics solver is used to solve the developed model. The hydro-thermal model was validated on experimental data drawn in our laboratory for moisture and temperature internal profiles of the product. Excellent agreement has been obtained between numerical and measured data for different… More >

    Modeling of Hydro-Viscoelastic State of Deformable and Saturated Product During Convective Drying

    R. Lamloumi1,2, L. Hassini1, G. L. Lecomte-Nana2, M. A. Elcafsi1, D. Smith2

    CMC-Computers, Materials & Continua, Vol.43, No.3, pp. 137-152, 2014, DOI:10.3970/cmc.2014.043.137

    Abstract A mathematical model was developed to simulate in 2D the spatiotemporal evolution of the moisture content, the temperature and the mechanical stress within a deformable and saturated product during convective drying. A comprehensive hydro-thermal model had been merged with a Maxwell model with two branches, assuming a viscoelastic material, a plane deformation and an isotropic hydric-shrinkage of the sample. A long sample of clay mixture with a square section was chosen as an application case. The transport and equilibrium properties of the product required for the modeling were determined from previous experiments which were independent of the drying trials. In… More >
