【摘要】 本文通过微机控制的自动气液界面测试系统对 VOD 过程中的气—液界面进行了研究。通过修正自由射流的轴向、径向衰减系数 K,β,建立了冲击射流、熔池气—液边界的数学模型。试验结果表明;这个自动测试系统可进行探针的自动扫描,多通道的数据采集及在线处理,具有采样速度快、精度高等特点。不仅适用于各种气—液界面的测定,更换探头后可测定反应器内的温度分布,速度分布、含气率分布等更多还原

【Abstract】 The study on gas-liquid interface in the VOD process was carried out by use of an automatic measuring system controlled by a micro computer,A mathematical model of the gas-liquid interface of the bath by impinging gas jet was established by means of modified decay factors K in axial and β in radial directions, Experimental results indicate that this automatic measuring system offers many advantages,such as automatical probe sweeping,fast and multi-channel sampling and on-line processing as well as high measuring accuracy,It can be applied not only to various gas-liquid interface measu- rements,but also to the determination of temperature distribution,velocity distribution and gas holdup in reactors,更多还原
