Computation of heat transfer in rotating two-pass square channels by a second-moment closure model Academic Article

abstract

• 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 180wall curvatures. The near-wall second-moment closure model provides accurate heat transfer predictions which agree well with measured data. (C) 2000 Elsevier Science Ltd. All rights reserved.
