Subject of research
The Magnus force plays an important role in translational movement with simultaneous rotation of solid particles in fluid; it causes the particle lateral movement normal to particle translational direction. Since accuracy of the available relationships for Magnus force is in some cases insufficient for numerical simulation (e.g. for particle saltation), the particle movement will be studied theoretically and experimentally to determine the effect of translational and rotational particle movements (expressed as particle Reynolds number and rotational particle Reynolds number) on dimensionless drag force, rotational drag force and Magnus force coefficient, respectively, for spherical particle with smooth or rough surface and also for ellipsoidal particle. Aim of the project is development of a new mathematical model and numerical simulation of the Magnus force, put together and experimentally verified relationships for the both drag coefficients of particle and Magnus force coefficient.
