Exploratory Experimental Investigation of Kerosene/Air Two-Phase Pulse Detonation Engine

摘要

摘要: 分别在内径为30mm和50mm的脉冲爆震发动机模型上,以煤油为燃料,以空气为氧化剂,成功地进行了两相爆震试验。试验中尝试了各种促进起爆的方法,获得了充分发展的脉冲爆震波。研究发现,在内径小于混合物胞格尺寸的爆震管内,可以形成充分发展的两相脉冲爆震波。通过采用提高煤油温度及对爆震管壁面加热的方法,对于点火及爆震起爆过程起着十分重要的促进作用。

Abstract: Using kerosene as fuel and air as oxidizer,two-phase detonation experiments were successfully conducted in two pulse detonation engine models with the diameters of 30 mm and 50 mm respectively.A variety of devices and means promoting the initiation of detonation were tested,and fully developed repetitive C-J detonation waves were obtained during the experiments.It's found that successful two-phase pulse detonations can be achieved in tubes with diameters less than cell size of mixtures.By means of heating kerosene and the tube wall,the ignition and the subsequent detonation initiation were promoted markedly.
