Abstract

The computational simulation results on the moisture transport within a porous media are presented in this paper. The porous media is simulated using models arranged in two patterns. The models consist of spheres representing the porosity of the media. The remaining void volume within the models is set as water. The spheres are arranged in two patterns, which are in-line cascaded and diagonally-cascaded. These pattern arrangements can aid the observation on the possible different transport paths of the moisture content within the porous media during drying operation. The models are simulated using boundary conditions such as outlet being set as atmospheric condition, materials of the spheres and water temperature. Simulation results are shown in contour plots around the spheres and void volume to illustrate the fluid velocity magnitude during the transport of the moisture content. Comparisons are also presented for the two models with different cascading patterns. Results show differences in magnitudes of velocity which indicates different moisture transport. These simulation results can also help distinguish the effects of different porosity arrangement on the moisture transport within the porous media especially during drying of the porous media. These models can also be used as initial simulation models for materials such as ceramic tiles.
