麻省理工学院化工系的Green教授提出了自适应化学理论AdapChem的概念。这种方法根据反应条件的不同,分别使用多个简化化学反应模型而非复杂的详细基元反应模型进行区域内的数值模拟。该法提供了在保证化学精度条件下,避免效率浪费的一条有效途径。然而,为了完善AdapChem,引入以往没有考虑过的辐射模型是有必要的。为此,该文使用的是离散坐标法并对复杂CH4空气火焰进行了模拟,得到了较为理想的结果。
Green professor at the Massachusetts Institute of Technology Department of Chemical Engineering proposed the concept of adaptive chemistry AdapChem. According to the different reaction conditions, this method uses multiple simplified chemical reaction models rather than the complex detailed elementary reaction model for numerical simulation in the region. This method provides an effective way to avoid wastage of efficiency while ensuring chemical accuracy. However, in order to improve AdapChem, it is necessary to introduce radiation models that have not been considered before. For this reason, this paper uses the discrete coordinate method and simulates the complex CH4 air flame, and obtains the ideal result.
