基于多维空间的燃烧平衡产物组成的计算方法

Calculation Method of Combustion Equilibrium Product Compositions Based on Multidimensional Space

为计算燃烧平衡产物的组成,在质量守恒关系的基础上,得到一系列基本可行解。根据吉布斯自由能,对基本可行解进行优化筛选,将筛选得到的基本可行解视为多维解空间的顶点,以吉布斯自由能降低为判据,利用基本可行解逐个与初始解线性组合,从而搜索得到最佳点,即为最终平衡产物组成。应用文献数据对计算结果的准确性进行验证。结果表明,该方法计算平衡产物的组成与文献数据基本一致,燃烧温度最大误差不超过3%。

To calculate the combustion equilibrium product compositions,a series of basic feasible solutions were obtained on the basis of conservation of mass.According to Gibbs free energy,the basic feasible solutions were optimized and selected.The basic feasible solutions obtained by selecting were considered as the vertex of the multidimensional space,the decrease of Gibbs free energy was considered as the criterion,the best point was obtained via search using linear combination one by one of basic feasible solution and initial solution,namely the final equilibrium product compositions were obtained.The accuracy of the calculation results was verified by the literature data.Results show that the compositions of equilibrium product calculated by this method are in agreement with the literature data,and the maximum error of combustion temperature is no more than 3%.
