Effect of Water-spout Number on Gas-steam Ejection Interior-Ballistics
摘要
Abstract
To study the gas-steam ejection power water-chamber, the Mixture two-phase model, k-ε turbulent model and zone moving and dynamic layering method were adopted to study the influence of water-spout number on the gas-steam interior-ballistics. The results show that,as the water-spout number increasing,the gas drag into bend tube and launch tube increases,and the water work-out time in ejection device decreases,and the maximum pressure peak during the ejection reduces. The water-spout number has a strong influence on the launch tube temperature from 0.1 s to 0.4 s,while it has little influence on tube temperature after 0. 55 s. For the water-spout number increasing, the missile ejection power decreases,and the tube-outlet time of missile delays,and the tube-outlet velocity decreases. The research can provide theoretical basis for the water injection design of gas-steam ejection.关键词
