Abstract: Experimental studies are made on the hemi – cylindrically blunted fins for Mach 2.2 to examine the effect of dimples on shock wave / boundary layer interaction. Flow field details around hemi – cylindrically blunted fin has been captured using oil flow visualization, measurements of static and total pressures and lambda shock has been captured by shadowgraphy technique. Studies show that the configuration indicate nonstart without any dimples whereas startup is observed with adoption of dimples on the leading edge of blunt fin. Studies have been also made by varying the number of holes, diameter of holes and height of blunt fins. In addition improvement in reduction of separation region has been observed.
