摘要

摘要: 为了研究雾化锥角对水反应金属燃料发动机一次进水反应的影响, 对水反应发动机一次进水燃烧情况进行了建模, 仿真了水反应特性和流场特性, 通过改变镁粒径、喷嘴位置和雾化锥角大小, 进行了对比分析。仿真结果表明, 水反应剧烈的位置液滴挥发作用也强烈; 温度场的分布与镁液滴分布有很大关联, 镁液滴多的位置流场温度低, 镁液滴少的位置流场温度高; 增大镁粒径, 水反应强烈的区域向后移动; 雾化锥角影响流场特性; 不同镁粒径条件下喷嘴最合适雾化锥角和位置不同。

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.
