Impact of porosity on the aerodynamic characteristics of the rotating cylinder
The study presents the results of experimental research to determine the drag and lift of the rotating cylinder with a porous surface in the range of airflow velocities 5...13 m/s (Re=40000....105000) at a constant rotation of the cylinder about its own axis. Also, the results of research drag and lift of a single rotating cylinder in the range of number of turnovers around its own cylinder axis 400...14000 r/min at a constant rate of air flow. It is shown that the coefficient of the drag and the coefficient of lift depends on the Reynolds number and the number of turnovers of cylinder. The dependence of the coefficient of aerodynamic characteristics from the degree of surface porosity of a rotating cylinder has been established.
