Numerical approach has grown its roots in almost all real world problems difficult to solve by experimentation. Real life turbulent flows that have no exact solution till this date can be modeled using CFD with appreciable accuracy, precision and reliability of results. Aerodynamics industry has now started looking towards this technique to discover the unexplored problems of turbulent flows. However,the reliability of results depend also on the certain model chosen for solution of a particular problem. This project explores the same matter and is about simulating turbulent flow over an axi-symmetric body using turbulence modeling techniques in CFD. A comparative study of one- and two- equation turbulence models has been carried out to judge the feasibility of using a certain model to achieve numerically precise results.
