Annotation: Modeling the physical process of air flow around a steel pipe barrel and determining its geometric dimensions and boundary conditions. Determination of the effect on the chimney of air flows that may vary depending on the superstructure, such as vibration dampers, windings, etc. The object of research is a steel, free-standing cylindrical chimney with a height of 30 m and a diameter of 1,5 m, without a lower cone and drawbars. By means of flow modeling according to the method given in the book A. N. Birbraer, A. Yu. Roleder «Extreme impacts on structures» 2009, obtained a visual picture of the distribution of speed, pressure, and the resulting turbulence near the calculated surface. Certain wind loads applied to the pipe stem allowed us to identify the main features of the pipe’s aerodynamics as a poorly streamlined body and determine the values of drag. The numerical calculation was performed in the Mathcad 15.0 program. Visual modeling of the effect of air flow on the structure under study was performed using the Comsol Multiphysics 5.4 software package.
