通过实验研究了多孔介质内往复流动下超绝热燃烧温度分布特性.对各种工况参数下,正反向流动半周期内,超绝热燃烧系统燃烧室内多孔介质轴向温度分布进行了测量.结果表明,不同物理参数条件下,燃烧室内的温度分布在半周期内变化具有不同的特点;一定条件下,燃烧室内有可能产生二维胞室结构热点. The temperature distribution characteristics of the super-adiabatic combustion under reciprocating flow in porous media were experimentally studied.The axial distribution of the porous media in the combustion chamber of the super-adiabatic combustion system was measured under various operating parameters during the half-cycle of positive and negative flows.Results It shows that under different physical parameters, the temperature distribution in the combustion chamber has different characteristics in the half cycle. Under certain conditions, the two-dimensional cell structure hot spots may be generated in the combustion chamber.
