In this work, the feasibility of flow pattern and oil hold up the prediction for vertical upward oil–water two–phase flow using pressure fluctuation signals was experimentally investigated. Water and diesel fuel were selected as immiscible liquids. Oil hold up was measured by Quick Closing Valve (QCV) technique, and five flow patterns were identified using high-speed photo...

In Lagrangian–Eulerian (LE) simulations of two-way coupled particle-laden flows, the dispersed phase is represented either by real particles or by computational particles. In traditional LE (TLE) simulations, each computational particle is assigned a constant statistical weight, which is defined as the expected number of real particles represented by a computational particle. If the spatial dis...

A core-shell gelatin-alginate composite used for intestine-released oral delivery drug carrier was synthesized through microfluidic technique. At the fixed continuous phase flow rate, the size of the core-shell gelatin-alginate microparticles increases with the dispersed phase flow rate, and monodispersity can be retained (the variation coefficient for the diameter distribution can be kept less...

The structure of an oil/water emulsion is known to depend on its preparation method. Here, we test whether the preparation protocol can be used to control the morphology of ‘‘model’’ blends of immiscible polymers compatibilized by a diblock copolymer. Two preparation protocols were tested. In the ‘‘double blending’’ protocol, a droplet-matrix blend was blended with additional drop-phase fluid. ...

to describe the rheological behavior of polymer blends using emulsionbased (palierne theory) as well as micromechanical models (coranapproach), two immiscible polymeric blend systems of poly(trimethylene terephthalate) (ptt)/polyamide-12 (pa12) and ptt/polyethylene (pe) having different levels of molecular interactions were investigated as model systems. the role of interfacial interactions, vi...
