“…Since the Maxey-Riley approximation breaks down near the walls, we introduce extra forces in the Maxey-Riley equation such that the correct particle dynamics is recovered as a wall or a singular corner is approached. Similar approaches have widely been used in the literature to complement the Maxey-Riley equation by dedicated particle-boundary models (Kharlamov, Chára & Vlasák 2008;Yang 2010;Agarwal, Rallabandi & Hilgenfeldt 2018;Davies et al 2018;Romanò 2019;Romanò et al 2019a;Agarwal et al 2021;Magnaudet & Abbas 2021).…”

“…In this regime, also longer ranging forces must have contributed to the attraction of the particle to the limit cycles. Candidates are the shear-induced lift forces from the moving wall (Cox & Brenner 1968;Ho & Leal 1974) and the repulsive force generated by the velocity gradient of the background flow in the wall-normal direction (Rallabandi et al 2017;Li et al 2020;Magnaudet & Abbas 2021).…”

“…Later, it was proven that the Segré-Silberberg phenomenon is caused by a combination of shear-induced lateral forces and a wall effect (Cox & Brenner 1968;Ho & Leal 1974), because a particle moving parallel to a boundary experiences additional drag and lift forces. In the case when a particle is moving far away and perpendicularly towards a boundary, it is subject to a repulsive force due to the wall-normal gradient of the background flow (Rallabandi, Hilgenfeldt & Stone 2017;Li et al 2020;Magnaudet & Abbas 2021). Closer to the boundary, in a distance of the order of the particle size, the particle experiences strong lubrication forces in the wall-normal direction (Brenner 1961).…”
