您要查找的是不是:
- Good agreement is achieved between the calculated and experimental static pressure data except the precombustion shock train region. 除预燃激波串区域外,计算数据与试验数据吻合良好;
- Isolators with different ratio of length to height (L/H) and divergence angle were investigated and the influence of back pressure on location of the shock train was analyzed. 在来流马赫数2.;3条件下,通过改变不同的反压来研究反压对不同长高比等截面隔离段和带扩张角隔离段激波串起始位置的影响。
- Results show that the increase of the asymmetry of the flow at the isolator entrance leads to the increase of the shock train length in the isolator for a gi. 研究发现,随隔离段进口流动非对称程度的增加,激波串+长度增加而隔离段耐受反压的能力下降。
- In this paper,the flow fields inside isolator has been simulated using three order up-wind MUSCL sche-me,and K-turbulence model,so it is easy to catch the shock train in the isolator flow field. 隔离段是双模态超燃冲压发动机实现双模态和模态转换的一个重要部件,同时,它把进气道和燃烧室隔离开,以防止燃烧室高压干扰进气道,引起进气道不启动。
- Methods Sterotaxic,shock training and polysomnography were used in the experiment. 方法采用脑立体定位、电击训练、多导睡眠描记技术。
- Numerical Simulation of Shock Train in a Constant Area Isolator 等截面隔离段中激波串结构的数值模拟
