【Abstract】 The heating scheme by supersonic counter flow mixing has been tested. The experimental results show that the temperature and pressure in a combustion chamber can be adjusted conveniently by controlling the rate of water flow sprayed in it and the ignition and stable flame of oxyhydrogen mixture can be easily realized by using double oxygen and hydrogen supply. The temperature distributions of the flow field measured by two-platinum lawrencium thermocouple certify that the heating scheme by counter flow mixing is basically feasible.更多还原
