摘要
对内燃机条件下湍流燃烧的高精度数值模拟研究进行了综合评述,其中涉及直接数值模拟(DNS),大涡模拟(LES)、小火焰模型(flamelet)、输运概率密度函数模型(PDF)等方法在内燃机湍流燃烧中的应用,对全面了解先进内燃机燃烧模式下,湍流火焰相互作用、喷雾燃烧火焰结构、低温冷焰、自燃和火焰传播模式、以及污染物生成机制的研究现状及前景提出了看法.
Abstract
This paper reviews high-fidelity numerical simulations of turbulent combustion under internal combustion engine conditions.Different modeling approaches are discussed including direct numerical simulation(DNS),large eddy simulation(LES),flamelet models,and probability density function(PDF)transport models.Applications of these methods to turbulent combustion in engines are summarized.This review provides comprehensive insights into the current status and outlook of studies on turbulent flame interactions,spray combustion flame structures,low-temperature cool flames,autoignition and flame propagation modes,and pollutant formation mechanisms in advanced combustion modes of internal combustion engines.
