Abstract
Cylinders are essential in constructing several engineering designs where fluid passes over them. Under varying environmental conditions, the fluid flows with impulse, affecting design structures considerably. This paper presents the numerical analysis of incompressible low-Re gusty flow with impulse inlet passing through three staggered cylinders. The problem is numerically simulated and investigated for two distinct variable factors keeping one constant at a time: inlet gust frequency and Reynolds number. The vorticity contours are obtained that provide information about local rotation. The streamlines are obtained to identify the wake region. The CL, CD, and St are computed. The results show a beneficial effect of variability in impulse intake velocity on the wake region generated between and behind the cylinders. It represents enhanced flow characteristics derived from low angular gust frequency value of intake velocity fluctuation.
