摘要
基于湍流射流理论，对转炉氧枪超音速射流的速度分布特征进行了理论分析，首次得到其动量传递系数ｋ＿ｊ和断面速度分布系数λ＿ｊ的关系为λ＿ｊ＜；
Based on the turbulent jet theory,the characteristics of velocity distribution for the supersonic jet of BOF oxygen lance are studied.The relationship between momentum transfer factor k_j and velocity distribution factor λ_j is derived as follows :λ_j<Verified by the experimental study,the empirical formula is given:
