rare effort to compare the performances of different κ-ω turbulence models in the body-fitted coordinates. In this work, we study the performance of three κ-ω turbulence models of Wilcox High Reynolds Number, Wilcox Low Reynolds Number, and Abid on a newly developed body-fitted algorithm which utilizes the physical covariant velocity components as the unknown dependent variables in its algorithm. To accomplish our purpose, we solve turbulent flow over a hill and compare the achieved results with available experimental data and others’ numerical solutions.
