Abstract To elucidate the key factor for the quantitative prediction of the shear thickening in suspensions in viscoelastic fluids, direct numerical simulations of many-particle suspensions in a multi-mode Oldroyd-B fluid are performed using the smoothed profile method. Suspension flow under simple shear flow is solved under periodic boundary conditions by using Lees–Edwards boundary conditions for particle dynamics and a time-dependent oblique coordinate system that evolves with mean shear… Expand
