Description
Summary:In this paper, considering the importance of incoming flow turbulence intensity into combustion chamber, tripping wire effect on the flow wake has been experimentally investigated within a linear compressor cascade. To do this, two wires were implemented along each blade and their effects on average velocity, turbulence intensity and vortices frequencies at Reynolds number 45500 were accurately considered. To measure wake parameters, one–dimensional hot wire anemometer was used. It is found that turbulence promoters increased the maximum turbulence intensity in blades wake and also reduced corresponding frequency in maximum amplitude and the Strouhal number, consequently.
