Double Diffusive Natural Convection in a Cylinder Filled with Moist Porous Grains and Exposed to a Constant Wall Heat Flux
要約
Fluid flow and heat and mass transfer induced by double-diffusive natural convection within a vertical cylinder filled with a moist granular product, opened at both edges and exposed to a constant wall heat flux, is studied numerically in this paper. The innovation of this study, in addition to the fact of considering a nonconfined geometry, consists of taking into account the evaporation/condensation phenomena within grains via the drying kinetics. The resolution of the equations set is done by the finite-volume method. The numerical code validation was carried out in a previous paper. We report here the time-space evolution of temperature, pressure, velocity, vapor concentration, and water content in the medium. The effect of varying external temperature, concentration, and wall heat flux was also studied.
