particles rising in a still fluid. All other parameters, such as the Galileo number (the ratio of gravitational to viscous forces)), we observe an entirely different 'helical'rise with completely unique features.
We experimentally investigate the effect of geometrical anisotropy for buoyant spheroidal particles rising in a still fluid. All other parameters, such as the Galileo number (the ratio of gravitational to viscous forces) ), we observe an entirely different ‘helical’ rise with completely unique features.
