传播速度
The momentum source of flow motion in the bath of tundish is the downward stream. The velocity of liquid stream is recorded by a high speed camera. The stream injects the surrounding liquid and forms a liquid-liquid jet with spread angle 10 °~ 12 °.
研究表明,注入的钢流下降时吸收周围液体,形成扩张角10°~12°的射流,是中间包内流动的动量源。
A new method of mini-refraction ray tracing is given based on a model of homogeneous medium tilted interface, by which formation velocity, its thickness and its apparent dip ( along the spread direction of mini refraction) could be calculated.
