摘要： 建立了重力势能驱动的旋流冶金反应器的数学模型,分析了反应器内部的流场和气体体积分数的分布.结果表明,数值模拟结果与物理模型实验结果基本吻合,验证了数学模型和计算过程的可靠性;重力势能驱动冶金反应器具有较好的旋流效果,其中前弯型叶片反应器旋流效果最佳.参数研究表明随着曲率半径的增大,混合管内的气体体积分数有较大幅度的提高,其中曲率半径为150mm的叶片反应器有较大的气泡出现.

Abstract: A mathematical model of the metallurgical reactor with swirling flow driven by gravitational potential energy was established to analyze the flow field and gas volume fraction. The results showed that the modeling results are basically consistent with the experimental results, thereby the reliability of the proposed model and the relevant computation program are verified. The reactor driven by gravitational potential energy can attain better swirling flow effect, and the swirling effect is the best when the vane has the form of forward bending. The gas volume fraction in the mixing tube increases greatly with increasing the curvature radius. When the curvature radius is 150 mm, some bigger bubbles appear in the vane reactor.
