Numerical Analysis of the Magnus Effect on the Forces Past an Axisymmetric Body at High Incidence

Rolling motion is the where a body flies at constant pitch angle α with respect to freestream velocity vector, while undergoing angular rotation p about its longitudinal axis. An effect of this appearance Magnus force and moment, which add static forces moments. One problem that arises high angles attack flow not symmetric in these conditions, leading non-zero side zero spin rate. Additionally, roughness induces roll on normal forces, therefore Then, low rates, prediction difficult assess due complex interactions moving walls, shedding vortices appear leeside. Computational fluid dynamics (CFD) an appropriate tool for investigating non-linear effects, particularly attack. It can help provide more accurate model moments insight into field. necessary use high-level turbulence models, transient calculations fine grids order capture field obtain their derivatives. The have shown symmetrical There are differences depending sign velocity. determine from total as there significant effects.
