| Abstract: | A low-speed blow down HDF-500 wind tunnel has been transformed in the meteorologtcal metrological verification station of Gansu Province. And its flow field characteristics are studied. According to calculate and analyze airflow velocity in the test section, the results show that the wind speed has a linear relation with the inverter frequency, and the range of airflow velocity is good enough for the modification. After the transformation of wind tunnel, the uniformity, stability, deflection and noisiness of the airflow meet the performance requirements, which satisfy the basic condition for metrological verification. |
