Numerical Modeling of Two-Dimensional Axisymmetric Laminar Diffusion Flamese rate chemical kinetics. We consider flames in which a cylindrical fuel stream is surrounded by a coflowing oxidizer jet. Unlike some models in which diffusion in the axial direction is neglected, we treat the fully elliptic problem. A discrete solution is obtained on a two-dimensional grid by comb腐烂 发表于 2025-3-27 18:26:51
Relevance of Nonpremixed Laminar Flames to Turbulent Combustionn complete chemical schemes, for fuels up to the lower hydrocarbons, along with detailed molecular transport properties. Typical applications include assessing the relative significance of elementary reactions and their influence on selected products, and simplifying the full schemes while retainingMorsel 发表于 2025-3-28 00:22:45
Laminar-Flame Structureasymptotic approaches to investigate the structure of steady flames, and, (iii) numerical approaches to the computation of unsteady flames. For each of these topics representative examples are discussed.miniature 发表于 2025-3-28 02:13:48
Discussion on Flame Structureetic and thermal data which are known only approximately. Likewise, experimental data, as recorded, may not conform strictly to conditions experienced by the flame. For example, in the case of stretched flames, the “bulk” or “nominal” strain rates used to plot data may differ, by as much as 50%, fro语源学 发表于 2025-3-28 06:51:18
Flame Stability.g. enhanced burning), or be of no consequence. In some cases the instability arises from interaction between the combustion field and the surrounding apparatus (e.g. singing flames , high frequency acoustic instabilities in rocket motors ); in other cases the instability is intrinsic to the cAbduct 发表于 2025-3-28 10:51:33
Stability of Laminar Diffusion Flames in Compressible Mixing Layersends on the structure of the mean flow, the first portion of this review will discuss our current understanding of the structure of diffusion flames in compressible mixing layers. The second portion of this review will discuss our present understanding of the stability of these flows. In both sectio
