Abstract

A three dimensional coupled heat and moisture transfer model for vibrating convective drying process of unsaturated porous medium was established. The aim of this paper is to study the effect of vibration on the drying of whole brick. A Three-dimensional unstructured Control Volume Finite Element Method (CVFEM) is developed. In order to simulate 3-D complex geometries, as application here the drying of whole brick, we developed Fortran modules to build the polygonal CVFEM mesh based on 3-D unstructured meshes generated by the free mesh generator Gmsh. The temperature, the liquid saturation and pressure distributions for whole brick were presented and analyzed for both cases namely with and without vibration. The results obtained state that the drying process is highly enhanced by vibration and the drying time is reduced by 20%.
