Abstract
Numerical analysis has been performed for turbulent flow with heat transfer in a rectangular duct with triangular cylinder placed near a wall by using an algebraic Reynolds stress model and the turbulent Prandtl number assumed to be constant in temperature field. Calculated results are compared with the experiment in order to confirm the validity of the presented model. It has been found that the calculation can reproduce reasonably the phase-averaged velocity profiles including vorticity. And calculation also predicts that the vortex affects the flow near the top and bottom walls. Adding to this, although the presented method underestimates Nusselt number in the region behind the triangular cylinder, two characteristic peaks of Nusselt number profile are predicted as well as the experiment. The compared results with the experimental and numerical data suggest that an algebraic Reynolds stress model has the potentiality to reproduce the turbulent flow with vortex.
