一维喷管化学反应流的吉尔方法研究

Gear method for calculation of one dimensional chemical reaction nozzle flow

建立了一维喷管化学反应流计算模型 ,并进行了数值求解 ,给出了喷管内一维化学反应流计算结果。采用吉尔方法解决控制方程组的刚性问题获得满意效果。计算中解决了化学反应流计算中初值难于给定和喉部条件难于确定等问题。并通过对氢氧发动机喷管的分析计算 ,证明了这种方法的正确性。

The one-dimensional chemical reaction nozzle flow was calculated numerically using a new mathematical method called Gear method The stiff control equations were solved properly Other difficult problems such as the initial value and the throat condition determination were solved
