Abstract:It is well known that particle aggregation can occur in a non-Newtonian fluid during sedimentation but this effect has not yet been documented in a quantitative way. We present an experimental study of the behaviour of a few non-Brownian particles settling along their line of centres in a weakly elastic and strongly shear-thinning fluid at low Reynolds numbers. Instantaneous velocities of the settling particles have been measured in three polymeric fluids that present different… CONTINUE READING
