An increasing number of industrially relevant suspensions, e.g., stabilized flows, backfill and codisposal systems, differ from conventional transport systems. Analysis of these suspensions is difficult due to their non-Newtonian behavior and increased particle/particle interaction. This paper presents data obtained in a 100 mm diameter pipe test loop using magnetic resonance imaging (MRI). The flows considered are stable suspensions of coarse particles in visco-plastic carrier fluids that are capable of statically suspending the solids. Particle concentration and fluid velocity maps are presented for a number of flow conditions which show that laminar flow of these suspensions is stratified rather than homogenous.
