摘要
对燃气镁合金熔化炉内的三维湍流气相燃烧场特性进行了数值模拟,湍流模型采用了标准k-ε双方程模型,湍流燃烧采用有限速率/涡耗散模型,辐射换热P1模型,数值方法采用SIMPLE算法,实现了燃烧过程的数值再现,特别考察了烧嘴位置和入口流量速度因素对炉内温度场和流动场的影响,并为熔化炉的结构设计提供了一些合理化建议,为其实际运行提供了有益的参考价值。
The three-dimensional gaseous combustion process in melting furnace for magnesium of gas is simulated. The fire characteristics in furnace are showed by numerical simulation applying the standard k-ε model to calculate the turbulent reacting flow, the finite-rate/eddydissipation model to study turbulent combustion, and P1 model to simulate radiation heat transfer. Especially, the effects of inlet flow and burner position on temperature and velocity field are investigated. On the base of these results, some advice for the physical design of melting furnace supply useful reference for the practice of the melting furnace.
