摘要
由于航空发动机燃烧室内复杂的物理化学变化,利用数学模拟的方法来计算其温度场,预测燃烧室出口温度分布,对减小燃烧室研制费用,缩短研制周期具有重要意义。采用fluent软件对某型航空发动机环型燃烧室在不同工作状态下的温度场进行了数值模拟,得到了不同工况下燃烧室的出口温度分布。计算结果能够很好地反应环形燃烧室温度场的特点,对预测环形燃烧室的出口温度分布有一定参考价值。
Because of the complicated physical and chemical changes in an aero - engine combustion chamber , the use of numerical simulation methods is of great significance to calculate the temperature field of the com- bustion chamber, to forecast the temperature distribution of the combustor exit, to reduce the development cost and shorten the development cycle. In this paper, the fluent software was used to simulate the temperature field of the annular combustion chamber and the temperature distribution of the combustor exit was obtained under different working conditions. The results is very good response to the temperature field characteristics in the annular combustion chamber, and it is valuable to predict the temperature distribution of the annular combustor exit.
