摘要:本文综述了空管道和置障管道内湍流预混燃烧的大涡模拟研究现状。从模型开发的角度,本文综合分析了重要的亚格子涡粘模型和亚格子燃烧模型的发展历程及其适用性。大涡模拟方法也被用来将流动及燃烧模型有机结合去再现现实生活中管道爆燃、爆轰以及爆燃转爆轰(DDT)现象。文章中所呈现的模型及其应用可以引导读者理解大涡模拟在管道爆炸方面的研究进展及其不足之处。

Abstract

This paper reviews the existing knowledge on the large eddy simulation (LES) of turbulent premixed combustion in empty tubes and obstructed tubes. From the view of model development in LES, this review comprehensively analyzes the development history and applicability of the important Sub-Grid Scale (SGS) viscosity models and SGS combustion models. LES is also used to combine flow and combustion models to reproduce industrial explosion including deflagration and detonation and the transition from deflagration to detonation (DDT). The discussion about models and applications presented here leads readers to understand the progress of LES in the explosion of tube and reveals the deficiencies in this area.
