摘　　要：对一直流低速风洞的试验段流场品质进行实验研究,利用IFA300热膜风速仪测量了风洞试验段的流场,获得试验段两截面中心线上速度和湍流度分布,结果表明,该风洞具有较好的流场均匀性和稳定性,具备了开展横流中的紊动射流实验研究的基本条件。In this paper,the quality of the flow field is studied over the test section in a simple low-speed wind tunnel.IFA300 hot-film anemometry is applied in the measurement of the flow field of test section in the wind tunnel.The mean velocity and the turbulent intensities are obtained.The result shows that the wind tunnel has a good uniformity and stability of the flow field,which can be carried out the experiment of the turbulent jet issuing into a uniform crossflow.
