摘要 基于计算流体力学(CFD)方法,建立了一种考虑冷却水进出口温差的冷却壁数值模型,并利用热态试验研究确立了更为准确的数值模拟边界条件。对比数值模拟与实验研究结果,两者吻合程度较高,验证了模拟方法的可靠性。同时也对是否考虑冷却水进出口温差的2种数学模型进行了比较,结果表明考虑冷却水温差模型有利于全面模拟冷却壁运行时各项指标。模拟结果也为高炉冷却壁在线智能监测提供了理论依据。 Based on computation dynamic fluid(CFD)method,the blast furnace(BF)stave numerical model was established,in which cooling water temperature difference between inlet and outlet was taken into account.Simultaneously,the boundary conditions of simulations were identified by hot experiment.According to the comparison,the results of simulation are in good agreement with the results of the experiment,which can be used as the basic mathematical model in stave monitoring.At the same time,two kinds of mathematical models with or without considering the cooling water temperature difference were compared.The results show that the model considering the cooling water temperature difference were conducive to comprehensive simulate the indicators of the cooling wall.And the simulation results provided theoretical basic for BF stave intelligent monitoring.
