| Abstract: | Critical nozzles are used to control the mass flow of hydrogen and oxygen, to keep the ratio of hydrogen and oxygen to be stoichiometrical. The mixing uniformity of co-axial hydrogen and oxygen jets satisfies the requirement of stable combustion well. The results of the experiments show that changing the mass flow of hydrogen and oxygen or adjusting the critical section area of the nozzle can change the gross pressure of the high enthalpy gas in the combustion chamber. These two kinds of methods can be used to build the high-enthalpy steam generator with simple structure and inexpensive cost. |
