查询词典 gauss curvature

It can be concluded that, when the jet is injected at positive angles, the initial section of the jet increases and the region affected by the jet decreases in the vertical direction; moreover, the circumfluence toward the jet exit becomes more obvious, and the separation events in the lee of the jet weaken. When the jet is injected at negative injection angles, it disarranges the flow upstream and the curvature of jet trajectories varies smartly along the flow direction.

结果表明：射流正向倾斜入射时，射流起始段增加，在垂直方向对主流场的影响区域减小，射流喷口上游位置处的&孔吸流动&更为明显，射流出口下游背风侧的分离现象逐渐减弱；射流反向倾斜入射，对上游流场的扰动增加，射流在弯曲段内曲率变化大。
