Iris Publishers - Journal of Civil and Structural Engineering Computational Examination of Aerodynamics Forces and Evolution of Vortex Shedding of Flow Past Three Square Cylinders at Two Symmetrical Vee Shapes Abstract The flow past three square cylinders at two symmetrical vee shapes has been investigated by a finite-volume method numerical technique. The two-dimensional computations have been performed for different Reynolds number (Re) ranging from 1 to 180 in order to consider different flow regimes; the steady, the periodic and the turbulent flow. The validation of the code with the available literature results regarded both the reliability of the computed solutions and the overall resulting efficiency of the methods. Velocity profiles, vorticity contours and integral parameters such as Strouhal number, drag and lift coefficients have been presented and analyzed. Steady and unsteady regimes of flow have been observed by monotonously changing the Re value, leading to the pred...
