利用含有29个反应式的简化模型对末端气体的焰前反应进行了模拟计算,可以计算出反应过程中的温度、浓度等细节,并由此预测爆震的发生。为实现上述目标,计算方法的选取是关键,本文利用了先进的吉尔(GEAR)算法,由于能够自动变步长地控制精度,在计算速度和计算精度上都得到了令人满意的结果
Using a simplified model with 29 reactions, the flame front reaction of the terminal gas was simulated and the details of the temperature and concentration during the reaction were calculated, and the occurrence of knock was predicted. In order to achieve the above goal, the selection of calculation method is the key. In this paper, the advanced GEAR algorithm is used. Since the control accuracy can be controlled automatically and in different steps, satisfactory results are obtained both in calculation speed and calculation precision
