摘要:
对某冲压增程弹用超声速双锥进气道流场特性进行研究,在风洞试验中得到合理的流场结构图谱及试验数据。采用块结构网格与二阶精度流场分区求解技术,对该超声速进气道内外流场进行数值研究。通过数值模拟得到了对应于不同出口反压和攻角情况下,超声速进气道内外粘性流场复杂的波系结构,分析了进气道内外流场的形成过程。结果表明:数值模拟得到的流场结构波系图与风洞试验纹影图一致,并且进气道扩压段静压分布以及进气道出口位置的总压分布与试验结果基本一致。
Abstract:
Flow characteristic of superson ic b-i cone inlet o f ram jet assisted range projectiles is studied, and reasonab le flow structures are also achieved through thew ind tunne l experim en.t App lying b lock structure grid and second-order zonal so lver method, the numerica l research on this inlet is presented. Complex w ave structures o f superson ic in le t at different backflow pressure and ang le o f attack are ach ieved by num er ical simu lation. The develop ing prog ress o f in ternal and external flow structure o f inlet is analyzed. R esu lts show that it is a lmost co inc ident o f numerica l flow structure w ith w ind tunne l experimental structure, and the d istribu tion o f static pressure at divergent sect ion o f in let and total pressure at ex it of inlet is also co incident compared w ith exper imenta l results.
