Precision analysis of the flow field measured in compressor rotor by using stereoscopic particle image velocimetry
This paper discussed the uncertainty analysis method of some SPIV results measured inside the compressor rotor.The convergence characteristics of the SPIV results of the three velocity components
the first-order results(vorticity) and the second-order statistics(the Reynolds stress) were investigated
and the measurement accuracy was analyzed.Then
the analysis of the main influential factors to the measurement accuracy of high-order statistics was carried out.At last
some advices for improving the measurement accuracy of SPIV in turbomachinery were given.
