Alfadhel B. Kasim ^[2] | Dr. Salah R. Al Zaidee ^[4]

Abstract: This paper studies the suitability of the CFD simulation to study the aerodynamic characteristics of bluff bodies. The bluff body aerodynamics is important to make improvement in understanding wind engineering. During the numerical simulation, the LES turbulence model and CFD Simulations were conducted by Autodesk Flow Design for associated with experimental results. Recent development of CFD technique makes it possible to predict the wind flows around a structure and a structure very close to the actual state. Thus, the practice of CFD even for wind-resistant strategy becomes practically realized now. The assessment of computational wind engineering (CWE) based on computational fluid dynamics (CFD) technique are making the numerical evaluation of wind loads on structures a potentially attractive hypothesis. This paper highlights the fundamental importance of validating CFD simulation from a configuration and a type of flow as close as possible to the topic of our studies. The computed drag coefficient, CD is estimated by evaluation with the experimental data.
