Shear cell simulations of the flow rheology of weakly wetted (a few volume percent liquid binders) particles are presented. The model involves spherical, poly-disperse particles with contact forces and a simple liquid bridge model, where the capillary bridges are isolated and the liquid assigned to a particle, which is assumed to be proportional to its surface, is equally distributed among all of its capillary bridges. Different liquid content and properties allows to predict the flow rheology when measuring shear strain and stress in a ring-shear cell. In this study, the focus is application in sand cores liquid binding materials.</p
