【摘要】 本文用数学物理模拟的方法研究了顶底复合吹炼条件下的熔池流场。本文的数学模型提出了二相区含气率分布的新公式及凹陷面上涡量的分布公式。数学模型预报的流场速度分布与激光测量的结果相符合。更多还原

【Abstract】 A mathematical model is developed for describing the flow field in liq- uids or melts agitted simultaneously by symmerically placed impinging gas jet and submerged gas stream The theoretically predicted velocity distributi- ons are found to be in satisfactory agreement with the experimental results by LDV method,更多还原
