Abstract

Abstract This study presents the results of the experimental study on hydrodynamics and heat transfer in separation zone in front and behind a single rectangular perforated rib mounted on a flat plate. The effects of perforation open-area ratio (β = 12%, 23.5%, and 44%) and the location of the hole on the rib (at the bottom, at the top, and in a staggered arrangement) on the mean and fluctuating characteristics of the turbulent dynamic and thermal boundary layers in the median section of the plate were examined. It was established that the stagnant and recirculation zones in the front and behind the perforated rib were shifted and became smaller or disappeared.
