燃油锅炉双通道旋流调风器数值计算

Numerical Calculation of Dual-passage Burner with Inlet Swirl

在建立双通道旋流调风器的物理和数学模型的基础上 ,利用有限差分法对调风器出口冷态空气动力场进行了数值计算 .计算表明 ,计算结论与实物试验结果基本吻合 ,所建模型及计算方法可供同类型调风器设计、试验及运行分析时参考 .

A physical model and a mathematical model for cold state aerodynamic field at the exit of swirl burner are established and calculated on the basis of FDM in this paper. Compared with the test, the numerical result is reasonable. It can be referred to the design and experiments of the similar kind of burner.
