底吹熔池流体流动的数学物理模型

A Mathematical and Physical Model of the Fluid Flow in A Bath Agitated by Bottom Blowing

摘要: 本文推导了底吹熔池流场中两相区的含气率公式和密度公式,修正了涡量传输方程中的源项,改进了前人关于底吹熔池流体流动的数模。本数学模型预报的结果与水模型中实验测量结果相符。

Abstract: New formulae have been derived for the void fraction and density ofthe two phase regions in flow fields of the liquid bath in bottom blowingsystems.Certain improvements have been proceeded to them odels developedby previous investigators. The resultant predictions have been shown insatisfactory agreements with the experimental data in present study.
