The results show that the most significant feature of turbulent free jet is the intermittently generation, shed of elliptic vortex rings, and once they generate they shed immediately.
研究结果表明：湍流椭圆自由射流的最显著特征是椭圆涡环的间歇产生、脱落，这些涡环一旦产生立即脱落。

The results show that the vortex board has the same cooling performances as vortex tube, which will lay a foundation for further study on the turbulent flow board.
