The present work describes a conceptual study of Staggered Cylinders of Square Cross Section by using Computational Fluid Dynamics. The overall pressure distribution over the cylinders were analyzed. The static pressure distributions on the group of cylinders with square cross sections in a uniform flow velocity of 13.5 m/s at a Reynolds number 4.13 × 104 is presented here. The group consists of three square cylinders of identical dimension. One square cylinder is placed centrally in the upstream side and the other two square cylinders are placed symmetrically in the downstream side. Surface pressure distributions on the cylinders are measured and compared for various longitudinal as well as transverse spacing of the cylinders. Wind loads are obtained in terms of drag coefficients, lift coefficients and total pressure coefficients. The outcome of this investigation was shown and computed by using ANSYS Fluent 16.
