In order to analysis complex turbulent shear flows, accurate predictions of mean flows and turbulent quantities are important thing in the fluid engineering. To obtain adequate predictions for such flows, a two equation turbulence model has been used, because the model gives more accurate results than other methods, and it is well-known that the calculation load is very economical using the model. Therefore, a two equation turbulent model is indispensable for the best design of the engineering application. Thus, the main objective of this study is to propose turbulent model which is not affected for various wall shapes. The proposed model is evaluated in some several turbulent flows. The proposed model gives good agreement with the experimental data.
