| 摘 要： | 以某钢铁企业360 m2环冷机为研究对象，以多孔介质模型为基础，对动量方程源项加以修正，对环冷机台车内气、固态采用局部非热力学平衡的双能量方程模型分别建立能量方程，基于计算流体力学软件Fluent并结合其二次开发平台，建立了适用于烧结矿冷却过程的数学模型。利用该模型对影响冷却过程的5个主要参数进行了模拟计算，并通过正交实验的方法对各参数进行了优化，得到了以提高环冷机的余热利用量为目标的最优运行参数的组合，通过与测试数据的对比验证了该模型的可靠性。

| Abstract: | Through studying a 360 m2 sinter cooler in an iron and steel company,a mathematical model for heat transfer in sinter cooling process is established.This model is based on the porous medium model,in which the momentum equation is corrected by Ergun equation and the energy equation is corrected by the two energy equations for local non-equilibrium thermodynamics.This model is solved with the user defined functions(UDF)and the user defined scalars(UDS)in the platform of computational fluid dynamics software,F... |
