초록

The effect of the cavity behind Rectangle Bluff Body in turbulent single-phase flow was studied using Particle Image velocimetry (PIV). The results for the time-averaged velocity showed a recirculation flow behind the bluff body. The horizontal location behind the bluff body where the time-averaged vertical and horizontal velocity components were zero was found at approximately 1.2H and the end of the re- circulation region was shifted upstream by effect of the cavity.
