Path oscillations and enhanced drag of light rising spheres
F Auguste, J Magnaudet - Journal of Fluid Mechanics, 2018 - cambridge.org
The dynamics of light spheres rising freely under buoyancy in a large expanse of viscous
fluid at rest at infinity is investigated numerically. For this purpose, the computational
approach developed by Mougin & Magnaudet (Intl J. Multiphase Flow, vol. 28, 2002, pp.
1837–1851) is improved to account for the instantaneous viscous loads induced by the
translational and rotational sphere accelerations, which play a crucial role in the dynamics of
very light spheres. A comprehensive map of the rise regimes encountered up to Reynolds …
