摘要
本论文针对HDF-500型风洞进行风速仪校准时的阻塞问题,提出了一种全新的阻塞修正方案。通过大量实验,对风速仪在标准风洞(国家气象计量站70m/s风洞)及HDF-500型风洞各个常用校准点的数据运用比较法进行分析,最终得到各个校准点的阻塞修正系数,并通过实验验证此系数的科学合理性。
In this thesis,a blockage correction scheme is proposed for the blockage problems during the calibration of anemoscope with being used in HDF-500 wind tunnel. Through a large number of experiments,the data of anemometers from various normal calibration spots when being used in the standard wind tunnels（national Meteorological metrology station 70 m/s wind tunnel） and HDF-500 wind tunnels are compared by using the comparative method,and the blockage correction coefficients for each calibration spots are finally obtained,through experiments we verified also the scientific rationality of the coefficients.
