Abstract In this work an experimental and kinetic modeling study on n-propanol and i-propanol combustion has been performed. New burning velocity measurements were carried out using the heat flux method at 1 atm over the temperature range of 323–393 K. Analysis of the temperature dependence was conducted with to verify the data consistency of the new and available data from the literature. Important inconsistencies were identified with the literature experiments performed using the spherical flame method and the nature of such inconsistencies was discussed. Moreover, a new kinetic mechanism, based on the most recent Konnov model and extended to include C3 alcohol isomers chemistry subset, was validated against new and all available literature data obtained at different combustion regimes. Rate constant parameters were carefully selected by evaluating all experimental and theoretical sources. Moreover, Sarathy et al. (2014) detailed kinetic mechanism was also tested. Overall, both kinetic models reproduce experimental data with good fidelity, but the presented model was found superior in representing ignition delay times data performed at high-pressure conditions.

丙醇异构体的燃烧：实验和动力学模型研究

摘要 在这项工作中，对正丙醇和异丙醇燃烧进行了实验和动力学建模研究。在 323-393 K 的温度范围内，使用 1 个大气压的热通量方法进行了新的燃烧速度测量。进行了温度依赖性分析，以验证文献中新数据和可用数据的数据一致性。使用球形火焰方法进行的文献实验确定了重要的不一致，并讨论了这种不一致的性质。此外，基于最新的 Konnov 模型并扩展到包括 C3 醇异构体化学子集的新动力学机制已针对在不同燃烧状态下获得的新的和所有可用的文献数据进行了验证。通过评估所有实验和理论来源，仔细选择速率常数参数。此外，Sarathy 等人。(2014) 还测试了详细的动力学机制。总体而言，两种动力学模型都以良好的保真度再现了实验数据，但发现所呈现的模型在表示在高压条件下执行的点火延迟时间数据方面表现出色。
