摘要
基于详细化学反应机理的燃烧数值模拟是当今燃烧领域的重要研究方向。由于燃烧问题涉及众多的化学反应和广泛的特征时间范围,如何实现燃烧问题的高效精确数值模拟一直是目前研究难点。本文将HDMR方法应用于模拟零维均质着火过程中,通过与完全求解刚性微分方程组的结果相比较,验证了HDMR方法在处理详细化学反应机理方面的计算精度与效率。
Numerical simulation with detailed chemistry is currently one of the most important directions of combustion research.The large number of chemical reactions and the wide range of characteristic time scales involved in the combustion process remain to be a great challenge to accurate and efficient combustion simulation.In this paper,the HDMR method was applied to the simulation of zero-dimensional homogeneous ignition process.The results from HDMR correlations were compared to those from solving full stiff ordinary differential equations.The accuracy and efficiency of the HDMR method for detailed chemistry were demonstrated.
