Abstract: The aim of this study is the numerical simulation of non-Newtonian fluid in an eccentric annulus with rotation of the inner cylinder. To evaluate the modeling accuracy, the computational domain has been defined such that the results of this study can be compared with experimental results of Nouri et al. (1997). At first the governing equations were selected according to the follow physics. Then by selecting the appropriate network, the physical equations were solved using CFD technique and finite volume method. The turbulent flow modeling has been performed using K-?, K-? and K- ?RNG methods. The obtained results of the study showed that the K-? method is compatible with experimental data of Nouri et al. (1997) and thus is a more appropriate method for numerical analysis of this type of flow.
