| 摘 要： | 利用摄像和量纲分析的方法研究了渣罐水模型中浸入式侧吹气体的最大穿透行为,从而为提高气液间的反应速率及氧枪的布局等问题提供参考.研究表明,当喷枪直径一定时,气体的最大穿透深度随气流动量通量的增加而增大,当动量通量相同时,液体的黏度越大,气体的最大穿透深度越小.气体无量纲穿透深度的经验数学表达式计算结果与实测气体穿透深度基本相符.

| Abstract: | The penetration behavior of immersion side-blowing gas flow in a slag lade water model is investigated by photography and dimensional analysis method,in order to provide a theoretical base for improving the reaction speed between gas-liquid interface and oxigen gunjet distribution.The results show that the maximum penetration depth of gas flow is increased with the increase of gas momentum while the diameter of oxigen gunjet keeps constant.If the momentum of the airstream is constant,the penetration depth of gas flow is decreased with the increase of the liquid viscosity.The maximum penetration depth calculated by the empirical equation is in agreement with the measured data from the experiments. |
