Abstract

This study investigates heat transfer and pressure drop for rib-roughened square channel without bleed. To optimize the shape of rib, CFD tools were used to model and simulate channel flow with a variety of rib angles and geometries. To validate simulations and determine the turbulence model, experimental results for two-pass channels with ribs at 45˚ angles with BR = 0 and Re = 25,000 was compared. It was found after conducting simulations with different turbulence models that SST turbulence model gave the best results.
