纵向涡发生器 longitudinal vortex generator ; LVG
The visualization showed that intensive longitudinal vortices formed right after the ribs in the discrete double inclined ribs tube. The vortices flowed downstream for nearly one tube diameter and the vortex intensity increased with increasing Reynolds number.
流动显示实验结果表明不连续双斜向内肋管管内存在较强的贴近壁面的纵向涡,纵向涡沿流向可持续约一倍管径距离,并且纵向涡的强度随雷诺数的增加而增强。
