摘　　要：以某烧结砖隧道窑为研究对象,为获得隧道窑冷却带散热温度场数据,建立了隧道窑窑壁-砖块-流体耦合传热物理模型与数学模型,采用FLUENT流体计算软件对其进行了隧道窑窑壁-砖块-流体耦合传热仿真,获得了窑内整体比较精确直观的温度场分布。仿真的结果表明:风速为5 m/s、孔隙率为0.5以及砖块适当稀码时,隧道窑冷却带降温效果较好,其与隧道窑烧成曲线冷却段吻合也较好,为风速调整、码砖方式和孔隙率的选择提供了理论依据,提高了烧成质量和生产效率。In order to obtain the cooling temperature field data in the tunnel kiln cooling zone, the tunnel kiln wall bricks-fluid coupling heat transfer physical model and mathematic model were established, taking a sintered brick tunnel kiln as the research object. The tunnel kiln wall bricks-fluid coupling heat transfer simulations were performed by commercial software FLUENT, and the overall accurate intuitive temperature field distribution was obtained. The simulation results show： the cooling effect on the tunnel kiln cooling zone is better when the draft speed is 5 m/s, the pore rate is 0.5, and the bricks arrangement is sparse, and that is also agreeable with the tunnel kiln firing curve＇s cooling segment. This information provides a theoretical basis for the adjustment of the draft speed, pore rate and bricks arrangement to improve the quality of bricks firing and productivity.
