This study provides an in-depth analysis of the aeroacoustic noise generation mechanisms associated with square cylinder aerodynamics. By conducting a comprehensive aeroacoustic analysis, we aim to uncover the intricate flow phenomena and noise production processes around a square cylinder. Utilizing ANSYS Workbench, we investigate the fluid dynamics and acoustics interactions at very low Reynolds numbers (Re) of 100 and 200. The research focuses on key factors influencing noise generation, including flow turbulence, unsteady pressure fluctuations, and the interactions between solid surfaces and the surrounding fluid. Our findings reveal a dipole noise pattern for flows at Re = 100 and 200, with maximum noise levels located at the top and bottom surfaces, predominantly influenced by lift fluctuations, and minimum noise levels located within the vortex street, influenced by drag fluctuations. These insights into the aeroacoustic characteristics of square cylinders offer valuable contributions towards understanding as well asgeneration of noisecontrol in various engineering applications, ranging from aerospace to civil engineering.
