摘要
In this paper, considering the importance of inlet flow turbulence intensity in the combustion chamber, the effect of flow turbulence on characteristics of the flow wake within a linear compressor cascade has been experimentally investigated. To this purpose, two wires were installed along each blade and their effects on average velocity, turbulence intensity and vortices frequencies at Reynolds number of 45500 were studied. One-dimensional hot wire anemometer was used to measure wake parameters. The results showed that turbulence promoters increased the maximum turbulence intensity in blades wake and consequently, reduced frequency of maximum amplitude and the Strouhal number.
