摘要：

The performance of a low-Reynolds version explicit algebraic stress model is assessed in predicting the turbulent flow and forced heat transfer in ribbed channels (under fully developed conditions) as well as impinging slot jets. The ribs are imposed in the main flow direction and periodic conditions are used in this direction, while no periodic conditions are used in the impinging cases. The calculated results are compared with the experimental results in a backward facing step, a ribbed channels and impingement with multiple slot jets. Both isothermal and constant wall heat flux conditions are imposed on the channel walls, and the turbulent heat fluxes are modeled using simple diffusivity and gradient diffusion type models. The agreement between the computed results and the experimental data is very good.
