Computation of Flow and Heat Transfer in Rotating Two-Pass Square Channels by a Reynolds Stress Model Conference Paper uri icon


  • A multiblock numerical method has been employed for the calculation of three-dimensional flow and heat transfer in rotating two-pass square channels with smooth walls. The finite-analytic method solves Reynolds-Averaged Navier-Stokes equations in conjunction with a near-wall second-order Reynolds stress (second-moment) closure model and a two-layer k isotropic eddy viscosity model. Comparison of second-moment and two-layer calculations with experimental data clearly demonstrate that the secondary flows in rotating two-pass channels have been strongly influenced by the Reynolds stress anisotropy resulting from the Coriolis and centrifugal buoyancy forces as well as the 180 wall curvatures. The near-wall second-moment closure model provides the most reliable heat transfer predictions which agree well with measured data.
