The purpose of this project is to develop a methodology for mathematical modeling and analysis of acoustic noise that arises when the viscous incompressible fluid flow flows around a group of bodies. A thorough overview of experimental studies devoted to the study of the noise occurring in the flow around of both a single cylinder and a group of cylinders was performed. A mathematical modeling of the flow around a group of two and three cylinders with regard to their different positions relative to the flow has been carried out. For each calculation case, the noise generated by the interaction of a group of cylinders with a flow was modeled. The non-stationary and time-averaged aerodynamic parameters of the cylinders in the group were obtained. Changes in the flow pattern were determined depending on the position of the group of cylinders in the flow. The differences in the noise parameters that arises when it is occur flow around a single cylinder and the flow around a group of cylinders were determined.
