从甲烷点火燃烧的GR I-M ech 1.2详细化学反应动力学模型出发,采用“准稳态”假设方法来对其进行简化,得到了包含18组分14步总包反应的简化反应模型。通过典型试验结果对比和基于均匀试验设计的校核计算结果比较可以看出,采用“准稳态”假设方法得到的简化反应动力学模型能有效地再现详细基元反应模型的反应机理,具有较高精度,是可靠而有效的。
Starting from the detailed kinetic model of GR I-M ech 1.2 for methane ignition combustion, the simplified quasi-steady-state method was used to simplify the reaction and a simplified reaction model with 14-step total reaction of 18 components was obtained. Through the comparison of typical test results and the comparison of the calculation results based on the uniform test design, it can be seen that the simplified reaction kinetic model obtained by using the “quasi-steady state” assumption method can effectively reproduce the reaction mechanism of the detailed elementary reaction model, High precision is reliable and effective.
