000014644 520__ $$2eng$$aWe study incipient motion of single spherical particles in shear flow over regular substrates at low particle Reynolds numbers. Experimental studies show a strong dependence on the substrate geometry. Numerical studies covering the entire range of particle spacings on quadratically arranged substrates show that rolling motion is always preferred to sliding motion. It also reveals how the effective zero level depends on the particle spacing. Taking into account the substrate geometry, we propose a model for the incipient motion at low particle Reynolds numbers that only relies on the effective zero level and compares well with experiments and numerics.
