000014690 520__ $$2eng$$aWe present simulations of the start-up of shear flow of 2D suspensions of rigid particles in viscoelastic fluids by applying a novel numerical method is applied that makes use of biperiodic domains. At Weissenberg numbers of 1 and higher, particle chaining is observed that leads to a decrease in bulk viscosity, an effect that was observed experimentally. Increasing the solid area fraction leads to the particle alignment occuring faster and the particles forming longer chains, causing a stronger decrease in bulk viscosity. In addition, at solid area fractions of 0.3 and higher, an increase of the bulk first normal stress difference is observed, which may be attributed to an increase in local shear rate in between the particle chains.
