An experimental model st ructure of wind velocity flow field in a circular low-speed wind tunnel is de-signed based on LDV velocity measurement technology.According to the measurement of different wind speed seg-ments,the appropriate and data processing methods are adopted to cond uct exploratory research on the flow charac-teristics of rectangular cross section air flow,and the data and legend are studied and analyzed to extract the effec-tive data values.The results show that this technique can not only accurately measure the nume rical distribution of the flow field,but also be used as an important measurement means to further understand and study the wind speed field of wind tunnel with different sections and structures and the field air volume measurement.
