Analysis of Flow Field Across Blunt Fin with Dimples – Experimentation
Authors: ,
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 the lambda shock has been captured by shadowgraphy. Configuration indicate nonstart. The effect of the number of holes, hole diameter and height of the blunt fin on the separation region has been investigated.
