    Abstract
  • To investigate the influence of spray angle on once water penetration reaction in hydroreactive metal fuel ramjet, a once water penetration combustion model of hydroreactive metal fuel ramjet is built and simulated. The hy-droreactive characteristics and the flow field characteristics are analyzed. The diameter of magnesium particles, and the nozzle′s location and spray angle are changed for comparative analysis. The results indicate that: in the position where hydro-reaction is fierce, the volatilization of water drops is fierce; the temperature distribution of flow field is related to the magnesium drops, i.e. the temperature of flow field is lower in the position with more magnesium drops, while the temperature is higher in the position with less magnesium drops; the increase in diameter of magnesium particles results in a backward movement of the fierce hydroreactive region; spray angle has an effect on flow field characteristics; and different magnesium particle diameter corresponds to different optimum spray angle and location of nozzle.
