Abstract:

The numerical simulation of spray combustion is widely encountered in power engineering，transportation，chemical and metallurgical，aeronautical and astronautical engineering. In recent years，the large-eddy simulation（LES）becomes more important not only in fundamental studies，but also in engineering application，especially in the modeling of spray combustion in internal combustion engines and gas-turbine combustors. LES can give the detailed development of flow and combustion processes and its statistical results are more accurate than those given by the RANS modeling; hence it is considered as a perspective CFD method. However，some problems，such as the sub-grid scale models and detailed experimental validation，remain to be solved. In this paper，

摘要：

液雾燃烧数值模拟在能源、交通、化工冶金和航天航空等工程中有广泛的应用，近年来，大涡模拟研究尤其受到重视，不仅在基础研究领域中，而且在朝着工程应用方向发展，特别是在内燃机燃烧室和燃气轮机燃烧室液雾燃烧数值模拟中的应用。目前液雾燃烧大涡模拟被认为是工程上最有应用前途的CFD数值模拟方法，可以显示流动和燃烧发展的动态过程，而且其统计结果比雷诺平均模拟（RANS）的更精确。但是还存在一些有待解决的问题，主要是亚网格模型和模拟结果的详细实验检验。本文就此领域的研究进展，包括作者最近的研究，进行了简要的评述，讨论了进一步研究的问题。
