摘要: 通过与实验结果的比较验证Fluent软件可以用于超音速流动中侧向喷流干扰特性数值研究.使用Fluent软件对超音速流动中不同喷流压力和攻角下侧向喷流干扰特性进行的数值研究表明,超音速流动中,随喷流压力和负攻角增大,喷流前的高压区明显增大,喷流的控制效果更好.喷流包裹作用的影响范围在90°弹面内.喷流压力增大,喷流包裹作用加强,影响范围增大.

Abstract: It was validated that Fluent can be used in numerical simulation on lateral jet interaction by comparing with the experimental results. Using Fluent, the lateral jet characteristics at different jet pressures and different angles of attack in supersonic flows is numerically investigated. The results indicate that in supersonic flows, with increasing of jet pressures, the high pressure region before lateral jet enlarged, and the wraparound effect strengthened. In the cases of angles of attack, comparing to windward side jet, the high pressure region before the leeward side jet enlarged, the jet wraparound effect in the region of leeward side moved forward, and the control of leeward side jet was more effective. The affected regions of wraparound effect is confined in regions from 0° to 90° on missile surface.
