非结构化自适应列表法(ISAT)方法以其高效、误差可控的突出优点在最近的使用详细反应动力学的燃烧计算中得到了广泛的应用。本文通过对ISAT基本原理的分析,讨论了ISAT存在的问题及改进的方法。在配对混合搅拌反应器(PMSR)和均质压燃(HCCI)发动机中,利用ISAT对不同的改进方案进行了计算比较,讨论了影响ISAT方法性能,如计算时间、内存占用和误差控制等方面的因素。结果表明逆向搜索方法可以显著提高ISAT的加速比,动态存储库方法可以大大降低内存的占用量。
The unstructured adaptive list method (ISAT) has been widely used in recent combustion calculations using detailed reaction kinetics due to its outstanding advantages of high efficiency and error control. This paper analyzes the ISAT basic principles, discusses the ISAT existing problems and improved methods. In the PMSR and HCCI engines, different improvements were calculated and compared using ISAT, and the performance of ISAT methods such as calculation time, memory consumption and error control were discussed the elements of. The results show that the reverse search method can significantly improve the ISAT acceleration ratio, and the dynamic storage method can greatly reduce the memory consumption.
