This work focuses on tyipical heat and mass transfer phenomena during the processing of products in the context of the packed-bed drying method products arranged in thick layers into dryers working in forced convection mode. The dryers are modeled as porous media at the macroscopic level. The simulations are carried out using the mass, momentum written in the framework of the Darcy's law approximation and energy equations applied for the different components.

Unsteady heat and mass transfers are important transport phenomena that are found in many engineering and industrial applications. In such systems, the variations in the fluid flow result in variations in the heat flux for fluid-solid temperature difference.

Convective heat transfer in turbulent flow in porous media is, in general, less understood compared to laminar and creeping flows. It is broadly integrated into industrial applications even though a lack of understanding in microscale. In the present study, we report a direct numerical simulation DNS based microscopic analysis of heat and fluid flow in synthetic porous media with an aim to link the macroscopic statistics and qualitative observations with pore-scale signatures of the same. DNS is conducted with two computational codes with a cautious validation on the microscale. The synthetic porous media are comprised of square cylinders in a staggered array. Macroscopic observation indicates an increased pressure loss and increased Nusselt number Nu as a result of high Reynolds numbers.

Show all documents Numerical modelling of thermo-hydromechanical THM in deforming porous media for subsurface systems A fully coupled model for simulating heat and mass transfer in deformable porous materials involving phase changes phenomena evaporation, condensation and la- tent heat transfer has been presented. The model based on a strong physical back- ground clearly identifies that the constitutive equations and other coefficients are needed to characterize the analyzed medium. The model results in a set of non- linear and coupled partial differential equations. Which are discretized in space using finite element method and finite differences method to solve for the gas pres- sure, p g , capillary pressure, p c temperature T and displacements u as primary vari- ables.

DOI: Abstract This research experimentally investigates the influences of electrical voltage, particle sizes and layer arrangement on the heat and mass transfer in porous packed bed subjected to electrohydrodynamic drying. The packed bed consists of a single and double layers of glass beads, water and air. Sizes of glass beads are 0.
