English Abstract

A computational study is performed on three-dimensional turbulent flow and heat transfer in a rotating rectangular channel with aspect ratio (AR) of 1o:1, oriented at 90° and 120° from the direction of rotation. Focus is on effects of high rotation and high-density ratios on the heat transfer characteristics of the 120° orientation. The finite volume code, FLUENT is used to predict the flow and heat transfer. Computational domain is meshed with fine grids to resolve the near wall viscous layer. The Reynolds stress model (RSM), which accounts for rotational effects, is used to compute the turbulent flow and heat transfer in the rotating channel. The effects of rotation and coolant-to-wall density ratio on the fluid flow and heat transfer characteristics are reported on a moderate range of rotation numbers and density ratios (0 < Ro < o.25 and 0.07 < Δρ/ρ < 0.4). The computational results are in good agreement with experimental data. The results show that the density ratio, rotation number and channel orientation significantly affect the flow field and heat transfer characteristics in the rotating rectangular channel. Flow reversal occurs at high rotation number and density ratio.
