Applications of the Laminar Flamelet Model to Turbulent Combustion in Diesel Engines

将湍流燃烧的层流小火焰模型应用于典型的柴油机扩散燃烧过程。

This builds up the fundamental of the flamelet model, and makes it possible to use the laminar flamelet model to simulate the complicated turbulent combustion process in diesel engines.

层流小火焰模型在近年来得到了广泛的应用，但是，在内燃机上的应用却不多，国内关于此方面的研究基本上仍是空白。

The coherent flamelet combustion model is first used in swirl chamber diesel engine.

首次将相关火焰微元燃烧模型应用于涡流室式柴油机中。

As the first attempt, this paper applies the laminar flamelet model to the typical diffusion combustion in diesel engines. A database of the laminar flamelet for a DI engine is built up in the phase space of the mixture fraction with the scalar dissipation rate as parameter.

以KIVA-3程序为基础，摒弃其原有的化学反应模型，模拟内燃机缸内多维湍流流场，并补充求解混合分数的时均值及其脉动均方值的湍流输运方程，得出各曲轴转角下混合分数的时均值及其脉动均方值的缸内空间分布。

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。
