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。
