Phase separation in a polymer dispersed liquid crystal (PDLC), consisting of a main chain liquid crystal (E7) and polymethyl methacryhte (PMMA), was studied by means of light scattering and optical microscopy. The PMMAm mixture exhibits an upper critical solution temperature (UCST), overlapping with a nematic-isotropic transition of the E7 liquid crystal. Several temperature quenches were under...

This paper describes the development of a three phase distribution system power flow program. The program is developed without any radial topology assumptions and thus can be used to solve both radial as well as meshed networks without any restrictions. Distributed generation, any combination of different types of loads including constant power, constant current and constant impedance with floa...

Mixed matrix membranes (MMMs) are attracting significant interest for pervaporation and gas separation applications. To better comprehend the impact of filler particles within polymer matrices, the species permeation mass transport was theoretically studied by numerical simulation using finite differences. The Fick’s second law of diffusion was solved for a three-dimensional MMM to obtain the c...

the purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. the size of the nano-emulsion and the ph of nano-emulsion were characterized. ultrasound has been used for preparing emulsion by 24 khz intensity for 120 seconds. prepared nano-emulsion was investigated by pa...

The Eulerian-Lagrangian approach is commonly used in modeling two-phase flows wherein liquid droplets, solid particles, or bubbles are dispersed in a continuum fluid of a different phase. Typically, the motion of the dispersed phase is modeled by assuming spherical, point-particles with models for added mass effects, drag, and lift forces. The effect of the dispersed phase on the fluid flow is ...
