Wake-Induced Oscillatory Paths of Bodies Freely Rising or Falling in Fluids (2012, methodology): “The case of a sphere, for which wake instability is the only candidate to generate oscillations, has lately been investigated numerically by Jenny et al. (2004) and experimentally by Veldhuis & Biesheuvel (2007) and Horowitz & Williamson (2010a).”
Paths and wakes of deformable nearly spheroidal rising bubbles close to the transition to path instability (2016, background): “For instance, it has been observed with light rising spheres [59] that increasing the Galilei number (the body-to-fluid density ratio being kept fixed) yields successively rectilinear, steady oblique, oscillating oblique, planar zigzagging, and chaotic paths.”
The effect of Reynolds number on the dynamics and wakes of freely rising and falling spheres (2010, background): “Such streamwise motions have been reported for rising cylinders (Horowitz & Williamson 2006, submitted), flat cylinders (Fernandes et al. 2007) and spheroidal bubbles (Mougin & Magnaudet 2006).”
Sedimentation of a dilute suspension of rigid spheres at intermediate Galileo numbers: the effect of clustering upon the particle motion (2014, background): “In the twoparameter space a variety of particle path regimes are encountered, involving vertical, oblique, time-periodic oscillating, zig-zagging, helical and chaotic motion, as shown numerically (Jenny et al., 2004) and experimentally (Veldhuis & Biesheuvel, 2007; Horowitz & Williamson, 2010).”
