The performance of three different low-Reynolds number turbulence models has been explored for the benchmark test of fully developed (periodic) flow in aribbed plane channel. Results are presented for two values of the Reynolds number (based on mean velocity and hydraulic diameter), Re=37,200 and Re=12,600, for which experimental data are available for the flow field and heat transfer, respectively. Comparison with experimental data includes the Nusselt number distribution along ribbed surface and profiles of mean velocity.
