%0 Journal Article %T FLUID DYNAMICS IN A GAS-STIRRED LADLE——A Separated Flow Model with Stochastical Trajectories %A ZHOU Ming LI Wencai Central Iron and Steel Research Institute %A Ministry of Metallurgical Industry %A Beijing %A China %J 金属学报(英文版) %D 1990 %I %X A separated flow model with stochastical trajectories has been developed to describe the fluidflow in a bubble stirred ladle.The bubble dispersion,turbulent characteristics and gas-liquidinteractions can be predicted by this mathematical model.The bubble flow as a dispersedphase is treated in a Lagrangian frame of reference and the analysis of the turbulent flow forliquid phase is conducted in a Eulerian field.The interactions between bubbles and liquidphases are considered as a bubble source term in the control equation for a continuous phase.The Monte Carlo sampling method is used to determine the bubble trajectories.The homoge-neous flow model is also taken into consideration so that it can be compared with the sepa-rated flow model.Numerical predictions using a water model of a ladle show that the pre-dicted results of the separated flow model agree satisfactorily with the experimental results,but the prediction of the homogeneous flow model are not in good agreement with the experi-mental results. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=AB188D3B70B071C57EB64E395D864ECE&jid=C19B08D052F5FD8445F4BB80A1A5D7BF&aid=58D41431AF8F956C8A28807043CD6C53&yid=8D39DA2CB9F38FD0&vid=38B194292C032A66&iid=59906B3B2830C2C5&sid=389106FB36CA8332&eid=663FF78B2ADE7A2D&journal_id=1006-7191&journal_name=金属学报(英文版)&referenced_num=0&reference_num=21
