“…Numerically speaking, scientists have been trying to quantify the complex rheology of laminar and Stokes flows of concentrated suspensions of rigid particles [24,25]. The flows of concentrated neutrally buoyant isothermal suspensions are known to exhibit a phenomenon of SIM in addition to a non-Newtonian behavior characterized by the presence of a first, and a second NSD N 1 and N 2 , respectively [8].…”
