end cavity meaning in Chinese
端部空腔谐振器
Examples
- Overlapping , nonoverlapping and overrelaxation ddm are discussed . electromagnetic ( em ) scattering by electrically large open - ended cavities is analyzed by ddm / fem - bie
讨论了重叠ddm 、非重叠ddm和超松弛ddm的迭代过程及其在eb一fem中的应用。 - The effects of reynolds number , back surface of nozzle , aft - dome configuration and degree of submergence on aft - end internal flow were studied by both cold gas simulation and numerical simulation . it is showed that the separated flow is sensitive to the change of reynolds number and aft - end cavity configuration
最后，利用冷流模拟与数值模拟相结合的方法，研究了雷诺数、喷管背壁形状、后封头形状和潜入深度对燃烧室尾部流场的影响，结果表明流动的分离对雷诺数和背壁区几何边界的变化很敏感。 - At the preliminary stage of burning the gas flows along the back surface of the submerged nozzle and no recirculation forms in the aft - end cavity . at the medium stage of burning a weak recirculation forms in the rear of aft - end cavity by the force of injection flow . at the end stage of burning the flow separates at the c ombustion channel and a strong vortex forms in the aft - end cavity
实验结果表明，在发动机工作过程中随着燃面的退移，燃烧室尾部的流动会发生很大变化，初始时刻背壁区加质流沿喷管背壁进入喷管，背壁区没有回流形成；中间时刻在加质流的驱动下背壁区后部形成较弱的回流；结束时刻气流在燃烧室壁面分离，背壁区形成强烈的回流。
