Numerical predictions of three-dimensional turbulent flow and heat transfer are presented for rotating two-pass rectangular channel with an aspect ratio (AR = 1:4). The aim of this study is to investigate the effect of the wavy walls of the heated part on the cooling enhancement. The influence of the wave length is also explored. Several calculations have been performed with Reynolds number (Re = 10 000), rotation number (R0 = 0.0 to 0.14) and coolant-to-wall density ratio (1-(T0 /Tw) is limited to 0.13. The commercial code ANSYS FLUENT is used to solve the steady 3D Reynolds–Averaged Navier–Stokes (RANS) equations. The performances of the k-omega SST and the second moment closure RSM models are evaluated by comparing their numerical results against the available experimental data. Detailed predictions of mean temperature, secondary flow and Nusselt number distributions are presented.
