摘要(Abstract)：

利用五孔探针对大、中、小三种流量工况下离心风机大宽度矩形截面蜗壳内部的三维流动进行了详细的测量 ,揭示了三种流量下该种蜗壳沿流动方向在不同位置处横截面内通流速度及动量矩的实际分布情况 ,并给出初步分析。
The 3 D flow in a centrifugal fan volute, which has big volute width and rectangular cross section, has been measured in detail by means of five hole probe with different flowrates. The measurement results show the distributions of angular momentum and throughflow in the fan volute. Preliminary analysis and discuss are presented based on the results
