Abstract

Computational Fluid Dynamics (CFD) used to simulate the flow of air through a model with two porous. Drawing geometry of the model was created in GAMBIT. Model consists of 3 sections, inlet, porous media, and outlets. Physical characteristics and properties of the material such as density, porosity, permeability, heat conductivity and heat capacity were obtained from previous researcher’s papers. The simulation was based on the formulation of the unsteady-state concentration to assess the ability of CFD tool for the development of flow through porous media. Comparisons were made on a model with 1 porous alumina, clay and both media together. Based on the simulation result, comparison in the decreasing rate of static temperature for insulated model and non-insulated model were made to prove the ability of CFD in simulating drying process. Airflow chooses to flow clay compared to alumina due to the low resistance and high porosity of clay. The magnitude of the velocity at the inlet was set at 30 m/s and the velocity magnitude increased to 68.8m/s at the inlet wall of clay. In addition, the surface pressure distribution for two porous media was simulated in 3 Dimensional.
