Abstract:In this paper, the structural model of the preheating zone of the full-scale roller kiln with an air spraying device was created, and the grid of this model was generated with the unstructured grid. FLUENT software based on CFD theory was used for simulating the gas velocity field in the preheating zone of the roller kiln and the standard K-ε two equations turbulent flow model was selected. The simulated results can describe the characteristics of gas velocity distribution preferably, which supplied the theoretic guide for the thermal operation for roller kiln.
Key words:CFD, numerical simulation, preheating zone of roller kiln, air spraying device, velocity field
