查询词典 piercing jet

The oscillation performance of jet, as oscillation frequency, is the essential data for designing the fluidic device, which is also the key factor that influence the coupling effect of fluidic device and receiving tube. This paper does experiment on the oscillation availability and frequency of feedback jet-oscillation gas wave refrigeration. As a conclusion, the jet oscillates only in a certain range of geometrical sizes and operating conditions. Under the condition of high pressure ratio, the frequency of the jet"s oscillation is only affected by the feedback tube"s length and chamber remarkably. Under the condition of low pressure ratio, the frequency descends with rise of the pressure ratio.

本文将跨音速正反馈射流振荡器与接受管耦合，对耦合后的射流振荡气波制冷机的可振性、振荡频率以及它们的影响因素作了实验研究，得出如下结论：射流只在一定的操作条件和几何结构尺寸范围内才能稳定振荡；射流的振荡频率在较高压比下只受反馈管长和反馈管容腔大小的显著影响，在小压比下随压比的增大而增加；其它结构尺寸和操作条件只影响可振性。

The results show that the erosion volume grows with the increment of pump pressure, there are best rock-breaking jet length, abrasive concentration and particle size. In low concentration, the erosion energy of post-mixed pulsed abrasive jet is close to the pre-mixed pulsed abrasive jet. After the external fluid is drawn in, the jet dynamic pressure increases by 7%, while pulse amplitude increases by 150%.

The central angle of the impingement fluid separated from the target surface became larger with the increase of jet Reynolds. And the separating angle also increased with the increasing ratio of the jet distance to the diameter of the jet hole, while the range of induced vortex became smaller.

试验中发现随着冲击雷诺数的增加，冲击气流与壁面分离处对应的圆心角增大，分离推迟；随着相对冲击间距值的增加，气流与壁面分离处对应的圆心角越来越大，相对于受限空间的大小，诱导涡的范围越来越小。

These measures are as follows: shorten the primary wind intervals to improve thermal load of the burner; reduce the size of hypothetical circle of contact to prevent the flame from splashing; use nozzles with larger height/width ratio to increase the effusive rigidity, so as to increase the jet flow depth of secondary wind into the main jet flow; use a higher primary wind velocity to increase its jet flow rigidity; use a special flame holder structure of the primary nozzle, so as to improve

The results showed that erectness of coupling pattern between upper-layer jet and low jet and a divergence area, which came forth in right of upper-layer jet provide favorable surrounding conditions. The most intensive moisture convergence, the strongest ascending movement and the most instable convection stratification all occurred in the rainfall center. The rainstorm occurred at the warm and wet side of the negative value center of the moist potential vorticity and relative MPV, which had certain indicative significance for the forecast of rainstorm areas.

结果表明：高低空急流的优势配置，耦合形势的建立以及高空急流右侧的强辐散场的存在为暴雨的发生提供了有利的环境条件；暴雨区中上升运动和水汽辐合均大于周围区域，中低层为对流不稳定层结；暴雨区位于湿位涡和湿相对位涡负值中心附近偏暖湿气流一侧，对暴雨落区预报有一定的指示意义。
