摘要:
气流湍流特性是衡量风洞流场水平的一个重要指标,也是影响模型动态测量数据精准性的关键参数。针对0.6 m连续式跨声速风洞,依托2种计算方法搭建了连续式风洞整流装置湍流计算模型,给出了2种方法的湍流度计算结果,并与实际测试结果进行了比较。分析发现,2种方法获得的气流湍流衰减变化趋势基本一致,湍流度衰减主要集中在前3层阻尼网,衰减约65%;方法一较实测最大值偏大约21%,方法二与实测最小值更为接近,虽然2种方法所得结果与实测值绝对值稍有偏差,但趋势及结果量级一致,因此可有效用于风洞整流装置优化设计。

Abstract:
Turbulence intensity in test section is an important index to evaluate the flow-field performance of wind tunnel, and provide guarantee for model's dynamics and accurate test. The prediction model should be established to evaluate the effect of rectification design to ensure the turbulence-intensity index. Two methods are introduced and used to predict the turbulence-intensity of a continuous and transonic wind tunnel comparing with test results. It was found that the turbulence-intensity variation trend obtained from the two methods is basically same, turbulence-intensity attenuation is mainly concentrated in the first three screens, about 65%, the result calculated by model-one is 21% larger than the measured value and the model-two result is much closer. These two methods can be used to optimize the design of rectifying device effectively although the results obtained by two methods are slightly different form the measured value.
Key words:    continuous and transonic wind tunnel    airflow turbulence    damping screen    design optimization
