Analysis and optimization of air flow distribution inside drying kiln systems contribute to the improvement of the final product quality. The present study reports on the threedimensional numerical solution of air flow within a drying kiln enclosure. The air flow field is examined in different configurations and operation conditions. Depending on the off/on switched fans, we obtain various air flow distributions. The simulation was performed using the COMSOL Multiphysics program using the k- ε turbulent mode in steady-state regime. The effect of the turbulence modeling is distinguished through a direct comparison between the results. The results highlight the position of the recirculation regions and the distribution of the air flow.
