    Abstract :

    The evolution of computational fluid dynamics over the years in solving wind engineering problems and its ability to predict wind flow over bluff bodies has reached great heights. Researchers are giving great contribution in their respective field in computational wind engineering to achieve great accuracy in wind flow prediction. Development of general codes for prediction of flow over building models are increasing in the past ten years. Turbulence modeling plays a major role in predicting the exactness of the flow along with geometry, domain size and discretization. RANS (Reynolds Averaged Navier - Stokes) model , DNS ( Direct Numerical Simulation ) model , LES ( Large Eddy Simulation ) model, are the models used to solve Basic turbulence equations. This article focuses on the k-ε turbulence modeling and its application in computational wind engineering. k-ε model is preffered more than the other models due to its ability predict flows with lesser resources and time efficiency.
