| description | In order to determine the influence of measurement rack on local airflow deflection angle of the direction field in low-speed wind tunnel flow field calibration, the design parameters of different measurement racks were studied by numerical simulations. By comparing the numerical simulations and test results under the same working conditions, the effectiveness of the numerical calculation method was verified. Based on the verified numerical calculation method, influence para-meters such as blocking degree of measurement rack, distance from the center line of test section, installation angle and length of the test probe on the measurement of local airflow deflection angle were studied. The corresponding influence law was obtained, and the influence model was established. The results show that the rack blocking degree, distance from the center line of test section, installation angle and length of the test probe have obvious effects on test angle of local airflow deflection angle. If the test design or test method is improper, it will directly lead to a large error in test results, and ultimately affect the accuracy of the direction field quality evaluation results. |
