根据某小尺寸压气机试验测试的需要,先后研制了两种(1#、2#探针)结构形式的总压、总温复合探针。分别介绍了两种探针的优缺点和校准结果,并对探针进行了数值模拟和出口流场测量,对比分析了两种探针测取的总压、总温及总性能间的差异。结果表明:两种探针均能满足小尺寸压气机出口流道堵塞比要求,有效地测取出口流场参数。 According to the needs of a small-size compressor test, two types of total pressure and total temperature probes (1 # and 2 # probes) have been developed. The advantages and disadvantages of the two kinds of probes and the calibration results are introduced respectively. The probe is simulated and the flow field of the outlet is measured. The differences between the total pressure, the total temperature and the total performance of the two kinds of probes are analyzed. The results show that the two kinds of probes can both meet the requirement of blockage ratio of exit of small size compressor and effectively measure outlet flow field parameters.
