Several rheological phenomena involve discontinuities of some sort. Three of such non-linear effects were discussed in this contribution. The yield stress in suspensions, the bubble volume-velocity jump in multiphase systems and the stress jump in vi

A procedure is described to build a slotted-plate device to directly measure the static yield stress of a suspension. The technique involves a balance as well as a linear motion platform. A slotted plate is suspended from the balance and is verticall

A nonlinear 3D model for mass transport into immiscible polymeric blends is developed by explicitly incorporating the interface dynamics into the transport equations. The interface is characterized, on a mesoscopic level of description, by a scalar Q

In this paper, we investigate, on two levels of description, the isothermal coupling: (i) between rheology and morphology in immiscible blends (A/B) and (ii) among rheology, morphology, and diffusion in mixtures consisting of an immiscible blend (A/B

In this contribution, we theoretically investigate the isothermal mass transport of a simple fluid into a blend of two immiscible Newtonian polymers. Using internal state variables, we derive a nonlinear formulation that addresses the effects of the

The barrier properties of Polyamide-6 (PA6)/High Density Polyethylene (HDPE) blends with and without compatibilizer prepared by ribbon extrusion were studied. The results show that the toluene diffusivity was improved by the addition of an interfacia

The effect of penetrant diffusion on the barrier properties of PVC geomembranes have been determined for the following organic environmental contaminants: benzene, dichloromethane, and trichloroethylene. The membranes experienced swelling to a degree

The deformation of nylon drops in polyethylene, with and without an interfacial agent, in an extensional flow has been studied. The presence of an interfacial agent reduces the size of the dispersed phase, and the deformation of the drop is reduced.

This study deals with the effect of impurities on the free rise velocity of gas bubbles in three Newtonian and eight non-Newtonian polymeric liquids. Experimentally, the rise velocities of air bubbles in liquids which contain concentrations of a surf
