摘　　要：应用相似与模化原理建立了高炉回旋区三维冷态试验模型,并应用三维激光相位多普勒分析仪(PhaseDopplerAnalyzer,PDA)对模型内流场进行了测量,同时用所建立的数学模型对流场进行了数值模拟。研究发现:涡流中心速度梯度出现突增的现象,数值模拟与试验结果比较一致。A 3D test facility of blast furnace (BF) cold raceway model was built based on the theory of similarity and modeling. The flow domain in the model was measured by the 3D laser phase Doppler analyzer (PDA). At the same time, using a mathematical model numerically calculated the flow domain. It was found that the velocity gradient seems to be increased rapidly in the vortex core. The experimental data approximately accorded with the data from numerical calculation.
