Abstract

In this study, the effect of rib structures on the turbulent flow and heat transfer have been investigated numerically. six different Reynolds Numbers, two different rib geometry (sharp-edged square and rounded-edged square) and four different rib layout are carried out. Streamlines close to the ribbed area, velocities, temperature distributions and Nusselt Number distributions on the bottom surface are investigated.
