Abstract

Computations were performed by using Version 5.5 of the Fluent-UNS code to compare three turbulence models in predicting the three-dimensional flow and heat transfer in a straight duct of square cross section with transverse, rounded ribs and bleed holes for film cooling. The turbulence models investigated are the standard k-ε model, the shear-stress transport model, and a differential Reynolds stress (DRS) model. For the standard k-ε and the DRS model, the two-layer low-Reynolds model of Chen and Patel was used in the near-wall region. For the standard k-ε model, computations were also obtained with wall functions applied at to two y + locations, 60 and 120. Results obtained for the heat transfer coefficient were compared with experimental data.
