CFD simulation study of air flow around the airfoil using the Magnus effect

The article presents a simulation study of air flow around the airfoil equipped with an additional rotary element, using the Magnus effect to change the air flow around it. For this purpose, a two-dimensional computational model for the airfoil without and with the moving element was made. The model was based on the airfoil NACA 8-H-12. The article describes a method of creating a model in two versions: without moving computational grid and with moving computational grid. Studies were carried out for a typical flow rate corresponding to the flow velocity around the gyroplane in a nominal flight speed conditions. Article shows a comparison of flows in both cases, and assesses the impact of the geometry that use the Magnus effect on the work of airfoil.
