Dense Suspension Jets – SuJets

This project aims at understanding the physics of the thinning and breakup of a liquid stream highly loaded with solid particles. Using model concentrated suspensions, it will built on experiments that will (1) go from quasi-statics to slow viscous dynamics, (2) monitor both stresses and deformations, (3) measure interphase stresses in relation with capillary confinement, (4) vary the particle aspect ratio and (5) address the case of ‘small’ repulsive particles. It is expected that these innovative these innovative concerns and observations will provide a ground for a solid physical picture of the breakup of dense, viscous, particulate suspension jets.
