在喷射搅拌流动反应器中，在900-1200 K的温度范围内，在1 - 10 atrn的压力范围内，针对较宽的燃料-氧气当量比（0.15 - 4.0），研究了丙烷的氧化反应。开发了计算机程序，使用化学动力学反应机理模拟实验数据。一个直接的方法来确定相对于速率常数的每种物质的摩尔分数的一级灵敏度被用来开发的动力学方案。本化学动力学反应机理能够重现我们的实验结果，虽然观察到一些差异的副产物，特别是乙炔。本机制的验证扩展到更高的温度，以描述激波管中丙烷的氧化。将不同作者在反射激波后得到的实验点火延迟与模型的预测进行了比较。在1200-1700 K温度范围内，计算结果与实验结果吻合较好.
The oxidation of propane was studied in a jet-stirred flow reactor in the temperature range 900-1200 K at pressure s extending from 1 to 10 atrn for a wide range of fuel-oxygen equivalence ratios (0.15 to 4.0), A comput er program has been developed to model the experimental data using a chemical kinetic reaction mechan ism. A direct method to determine the first orde r sensitivities of the mole fraction of each species with respect to the rate constants was used to develop the kinetic scheme. The present chemical kinetic reaction mechanism is able to reproduce our experimental results, although some discrepanci es are observed for the minor products, particularly for acetylene. The validation of the present mechanism is extended to higher temperatures, in order to describe the oxidation of propane in shock tubes. The experimental ignition delays obtained behind reflected shock waves, by various authors, are compared with the pred ictions of the model. Good agreement is found in the temperature range 1200–1700 K.
