Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Based on the simplified format of the Reynolds stress equations, a fire-new rotational-modification method for the anisotropic turbulence model has been deduced and presented. How to make use of this new model has been discussed in detail. A three-dimensional Navier-Stokes code with this new rotational modified turbulence model and the standard k-ω turbulence model have been used for the prediction of flow and heat transfer characteristics in a rotating smooth square channel. The Reynolds number Re based on the inlet velocity of the cooling air and hydraulic diameter is 5000 and the Rossby number is 0.176 which is based on the inlet velocity and rotation speed. The calculations results of using three turbulence models have been compared with the experimental data. The results show that the numerical results of using the new rotational modified turbulence model with β=0.1 yield a better agreement with the experimental results than that of using the standard k-ω turbulence model.
