Flow and heat transfer in rotating two-pass rectangular channels (AR=2) by Reynolds stress turbulence model Academic Article uri icon


  • Numerical predictions of three-dimensional turbulent flow and heat transfer are presented for a rotating two-pass smooth rectangular channel with channel aspect ratio of 2:1. The focus of this study is to investigate the effect of rotation, channel orientation and the sharp 180 turn on the flow and heat transfer distributions. Two channel orientation, are studied: = 90 and = 135. A multi-block Reynolds-averaged Navier-Stokes (RANS) method was employed in conjunction with a near-wall second-moment turbulence closure. The Reynolds number (Re) is fixed at 10,000 while the rotation number (Ro) is varied from 0 to 0.22. Two inlet coolant-to-wall density ratios / are studied (0.115 and 0.22). The numerical results are compared with the experimental data for both stationary and rotating two-pass rectangular channels. 2002 Elsevier Science Ltd. All rights reserved.
