“…Chaiyo and Rattanadecho [9] showed the numerical analysis of two dimensions for microwave melting of icesaturated porous medium which was filled in a rectangular waveguide (TE10) at 2.45 GHz. Cheng et al [10] used the enthalpy porosity technique based on the finite control volume method to solve the natural convection during phase change of binary mixture (carbon-iron), and the Navier-stokes equation was also applied by Boussinesq approximation technique. Furthermore, there are also interesting research groups including: Iwaki [11], Rihan and Abd El-Bary.…”

The purpose of this study is to investigate the numerical model of heat and mass transfer during freezing process for various arrangements of porous layers within a rectangular enclosure. The numerical model for energy conservation in solid and liquid regions was solved by using the differential equations under the local thermal equilibrium condition (LTE). All governing equations with the entire computational domain including all regions were solved by the finite element method. A simulation model was established through the analysis based on two constraints: 1) the Boussinesq approach which considered in buoyancy term with the function of density inversion and 2) the local thermal condition. According to this model, the numerical predictions of velocity field in unfrozen zone reveal different flow behaviors resulting from the freezing load and layer arrangement. Some cases, such behaviors also depend on the operating time due to the increase of the frozen layer thickness which affect permeability. The velocity change in unfrozen zone also results in the moving rate and the shape of freezing front. Furthermore, it indicated that the characteristics of freezing process were dominated by freezing load and permeability in each layer. The 2-D model from this study reasonably correspond to the literatures.
