摘要
均质压燃(HCCI)发动机由于其突出的优越性已成为世界范围的研究热点,数学模拟在其中发挥着日益重要的作用.因此,对近年来HCCI数学模拟研究的进展做了较全面的评述.着重介绍了化学反应动力学模型的研究方法和最新成果.对HCCI发动机计算机模拟的发展现状按单区模型、多区模型和多维模型分别进行了讨论.前二者在HCCI总体燃烧特性预测与分析方面已取得了显著的成绩;而后者由于计算机资源的限制,目前尚处于发展初期.最后,针对该领域存在的问题和今后重点研究方向提出了建议.
Due to its outstanding advantages over the traditional engines, HCCI technology has been the subject of the worldwide extensive research over the last few years. As a powerful tool, mathematical modeling plays an important role in the HCCI research and development. This paper presents a comprehensive overview of the state of the art in HCCI simulation with emphasis on the chemical kinetic models. The current progress in the computer simulation of HCCI combustion is briefly described and it is shown that the single- and multi-zone models have achieved remarkable success in predicting the global performance of HCCI engines, while the multi-dimensional models are still in their beginning stage. The existing problems and difficulties in HCCI modeling are pointed out and suggestions for the future research directions in this area are provided.
