摘　　要：采用计算流体力学方法对全偏心型贯流式风口内冷却水流场进行了三维数值模拟,分析了给水工艺参数和风口构造对冷却水流动的影响。通过模拟找出了易发生冷却死区的部位,依据计算结果提出了改进风口结构设计的措施,为全偏心型贯流式风口的设计和改进提供了理论依据。This paper shows a 3D numerical simulation of inner cooling water flow - field in full eccentric cross -flow BF tuyere by means of hydrodynamics calculation method, and makes an analysis of the influence of feedwater technologic parameter and tuyere structure upon cooling water flow. Through simulation, the position where cooling blind area occurs easily is found. And measures taken for improving the design of the tuyere structure are put forward in accordance with the calculating resuhs, which provide theoretical basis for the improvement of the full eccentric cross - flow BF tuyere.
