散

The comparisons between nitrogen oxides predictions and measurements were made,and the influence of Reynolds number, scalar dissipation and flamelet time on the formation of nitrogen oxides was discussed.

将氮氧化物的计算结果和实验数据进行了比较，并探讨了Reynolds数、标量耗散和火焰面时间对氮氧化物排放的影响。

The laminar flamelet model has been widely used in the recent years, but its application to the internal combustion engine is still scarce. The domestic investigation in this aspect is almost blank.

本文作为初步尝试，将层流小火焰模型应用于典型的柴油机扩散燃烧过程，以一台直喷式柴油机为对象，分别以碳十二烷与空气的单步反应和正庚烷与空气的多步反应为机理，以混和分数为自变量，以标量耗散率为参数，建立相空间中组分质量分数瞬时值及温度瞬时值的二维层流小火焰数据库。

On the respect of partially-premixed combustion research, we systematically studied the structure of partially-premixed flames in counter-flow and coaxial jet flow by using direct calculation and flamelet modeling.

在部分预混燃烧研究方面，本文结合火焰面模型和直接求解的方法，在对撞射流流场和同轴伴流流场中系统研究了部分预混火焰的结构特征，提出以预混燃料的当量比和当量混合标量耗散率作为描述部分预混火焰结构变化的参量的观点，并比较了它和非预混火焰的异同。

Firstly, the two parts are solved separately, and the results are then coupled together. Because the thickness of the combustion reaction zone at high Re and Da numbers is less than the turbulent diffusion scale in diesel engines, the flame is extremely thin, its micro-structure keeps the laminar structure, so the turbulent flame can be regard as the ensemble of locally one dimensional, thin laminar flamelet embedded within the turbulent flow field.

由于柴油机中在高雷诺数和高Damkoeler数的情况下，燃烧反应区厚度小于湍流耗散尺度，火焰极薄，其微元保持层流结构，因此，湍流火焰可视为嵌入湍流流场内局部具有一维结构的薄的层流小火焰的系综，这便构成了层流小火焰模型主导思想，同时也使层流小火焰模型模拟柴油机湍流燃烧过程成为可能。

He chewed my head off about the "threadsoul", the "causal body,""ablation," the Upanishads, Plotinus, Krishnamurti,"the Karmic vestiture of the soul,""the nirvanic consciousness," all that flapdoodle which blows out of the East like a breath from the plague.
