根据实际尺寸构建了设有喷风装置的辊道窑预热带窑体模型，采用非结构化网格对模型进行网格划分，然后利用基于计算流体力学(CFD)理论的Fluent软件，选用标准K-两方程湍流模型，对预热带内气流速度场进行了数值模拟。结果表明，模拟计算结果能较好的体现窑内气体流动特征，可为辊道窑热工操作提供理论指导。
根據實際呎吋構建瞭設有噴風裝置的輥道窯預熱帶窯體模型，採用非結構化網格對模型進行網格劃分，然後利用基于計算流體力學(CFD)理論的Fluent軟件，選用標準K-兩方程湍流模型，對預熱帶內氣流速度場進行瞭數值模擬。結果錶明，模擬計算結果能較好的體現窯內氣體流動特徵，可為輥道窯熱工操作提供理論指導。

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 ifeld in the preheating zone of the roller kiln and the standard K-ε two equations turbulent lfow 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.
