段法与三元模型在连续加热炉上的应用研究

Application on reheating furnace by using zonal method and ternary model

针对连续加热炉,先建立段法模型,通过改变表面段规格寻找准确解,并以该结果为基准衡量三元模型。而在三元模型下,通过考察模型段和炉气黑度变化,寻找温度场的变化规律,最终得到三元模型的合理解。

Aim to the reheating furnace the zonal method is developed. The exact solution is solved by changing the zone size. Then using the solution as a criterion to measure the ternary mode. In the other hand, based on the ternary model , the changes of model zones and gas emissivity values are inspected for searching the regxdation of temperature zone changing. Finally, the accurate solution for ternary model is obtained.
