大旋涡的模拟(LES ) 在它的快速的发展中并且作为 CFD 方法的产生在工程使用了的一可能的秒被认出。二阶段的流动和燃烧的大旋涡的模拟为设计应用是特别地重要的。包括现在的作者,一些调查者在煤气汽轮机的燃烧室和内燃机在水花燃烧的 LES 上给他们的评论。然而,直到现在,仅仅一些报纸与有关在煤气粒子的流动和燃烧的 LES 上最先进。在这份报纸,在复杂煤气粒子的流动和煤燃烧的 LES 的进展的评论被介绍。不同亚格子规模(SGS ) 压力模型和燃烧模型被描述,一些主要结果被总结,并且一些研究需要被讨论。
Large-eddy simulation (LES) is under its rapid development and is recognized as a possible second gen- eration of CFD methods used in engineering. Large-eddy simulation of two-phase flows and combustion is particu- larly important for engineering applications. Some investigators, including the present authors, give their review on LES of spray combustion in gas-turbine combustors and internal combustion engines. However, up to now only a few papers are related to the state-of-the-art on LES of gas-particle flows and combustion. In this paper a review of the advances in LES of complex gas-particle flows and coal combustion is presented. Different sub-grid scale (SGS) stress models and combustion models are described, some of the main results are summarized, and some research needs are discussed.
