Two phase combustion flow for water ramjet containing magnesium

Two-phase combustion flow model on metal fuel/water ramjet was established,and the method of modifying the inlet temperature of gas by combustion efficiency was put forward.The flow distribution was calculated on the ideal and actual operation process of the experimental motor.The error was analyzed through the comparison between the numerical and experimental results.The result shows the flow distribution is more reasonable through the model of modifying the combustion temperature,and the evaporation effect and the heat loss are important factors which influence the motor performance,also because of the exist of condense magnesium the combustion efficiency of computation is greater than experiments.
