【摘要】 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.更多还原

【Abstract】 An experimental study was carried out on temperature distribution characteristics of superadiabatic combustion in porous media with reciprocating flow(RSCP).The temperature distributions inside the porous medium combustor were measured under various working parameters.The experiment results show,during combustion process,under various working parameters,the characteristics of periodic evolution process are different;the double wave structures of the hot-spot structure can be found under some conditions.更多还原
