Abstract

The influence of preliminary ionization and excitation of molecules of a fuel–air mixture when exposed to an electron beam created in an external electric field on increasing the intensity of combustion processes is considered. To study the effect of electron beam plasma on the combustion of a propane–air mixture, a series of experiments were carried out. The characteristics of the propane–air mixture are determined before and after irradiation with an electron beam in the presence and absence of an external electric field. The boundaries of the combined effect of an electron beam and an external electric field are found to increase the efficiency of combustion of a propane–air mixture in a subsonic flow. A physical model of processes in a non-self-sustaining discharge in a subsonic flow of a combustible mixture under known experimental conditions is developed.

加速电子束和外部电场对丙烷-空气混合物在亚音速气流中燃烧的影响

摘要

考虑了当暴露于外部电场中产生的电子束时燃料-空气混合物分子的初步电离和激发对增加燃烧过程强度的影响。为了研究电子束等离子体对丙烷-空气混合物燃烧的影响，进行了一系列实验。在存在和不存在外部电场的情况下，在电子束照射之前和之后测定丙烷-空气混合物的特性。人们发现电子束和外部电场的联合效应的边界可以提高丙烷-空气混合物在亚音速流中的燃烧效率。开发了已知实验条件下可燃混合物亚音速流中非自持放电过程的物理模型。
