摘要
由气固两相流的多流体模型、气相湍流Ｋ－ε模型和颗粒湍流代数模型出发，对射流细分氧煤燃烧器在高炉直吹管中的气固两相流进行了数值模拟，得到了其中不同截面上气相速度场、颗粒速度场及浓度场。与实验结果比较，数值模拟结果较为合理。
mathematical model of the gas-particle now in a blast blowpipe with a multi-jet oxy-coal burner is developed by the multi-fluid model of gas-particle now, K-B model of gas turbulent flow and algebraic model of particle turbulent now,and then the gas velocity field and particle velocity and concentration field on various sections are obtained. Numerical modeling shows reasonable by comparing with experimental results.
