Abstract

In this study, a method was developed to calculate the radius of a spherical expanding flame, with the goal of mitigating the effects of the ignition electrode. This approach allows for a swift determination of the ignition electrode's influence on the spherical expanding flame. It also facilitates accurate computation of the flame radius and offers a systematic means to validate the derived laminar burning velocity. Using this method as a foundation, an evaluation system was established to examine factors that could impact the method's results. Findings suggest that the laminar burning velocity determined by this method aligns more closely with numerical simulations and experimental data from referenced studies. For spherical expanding flames with convex and concave contours near the ignition electrode, the mean flame radius decreases by 0.57% to 1.22% and increases by 1.37% to 2.95%, respectively.

考虑到点火电极影响的球形膨胀火焰半径计算方法

本研究开发了一种计算球形膨胀火焰半径的方法，目的是减轻点火电极的影响。这种方法可以迅速确定点火电极对球形膨胀火焰的影响。它还有助于精确计算火焰半径，并为验证推导出的层流燃烧速度提供了系统方法。以该方法为基础，建立了一个评估系统，以检查可能影响该方法结果的因素。研究结果表明，该方法确定的层流燃烧速度与数值模拟和参考研究的实验数据更为接近。对于点火电极附近具有凸轮廓和凹轮廓的球形膨胀火焰，平均火焰半径分别减少了 0.57% 至 1.22%，以及增加了 1.37% 至 2.95%。

期刊介绍： Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
