Multiphase waterborne polymer particles provide advantages in more demanding applications, and their performance depends on particle morphology. Currently, no dynamic model for the prediction of the development of the morphology of multiphase latex particles is available. In this work, a model was developed for the prediction of the dynamic development of the morphology of multiphase waterborne...

Background and Objectives: Despite superior privileges that multiphase motors offer in comparison with their three-phase counterparts, in the field of multiphase linear induction motors (LIMs) few studies have been reported until now. To combine the advantages of both multiphase motors and linear induction motors, this paper concentrates on multiphase LIM drives considering the end effects. Met...
Bubble column reactors are used in a wide variety of applications such as multiphase bioreactors, catalytic slurry reactors, and absorption processes. The superficial gas velocity-gas holdup relationship and transition point are two important parameters for characterizing the hydrodynamics of a bubble column reactor. In this study, systematic investigation of a nitrogen - water - glass bead...
The role of direct numerical simulations (DNS) of multiphase flows, where all continuum length and time scales are fully resolved, in validation and verification of models for the average flow, is discussed. Although DNS are usually limited to relatively small problems and are generally impractical for predictions of full-scale multiphase systems, DNS offer unprecedented data and insight. Indee...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
Subcooled flow boiling was experimentally investigated in a horizontal annulus with temperature-controlled surface and transparent outer pipe facilitating visualization. Boiling occurs on copper tube diameter of 12 mm an 2 gap. Refrigerant R245fa is used as working fluid. The focus this study to explore the effect heat flux variation patterns at approximately constant inlet conditions fluid (fi...
The immobilized enzyme lipase acts as an efficient, selective and durable catalyst in the direct transformation of unsaturated carboxylic acids to epoxides, which are used chemical intermediates bio-lubricants. Experimental data obtained from epoxidation a model molecule, oleic acid laboratory-scale isothermal batch reactor were critically evaluated mathematically modelled most precise way. Sev...
The multiphase leisure experience looks at the experience as a five phase process that includes anticipation, travel to, onsite behavior, travel from, and recollection. This continuum depicts a dynamic experience, one that evolves and matures across the five phases. The purpose of this study is to take this model and apply it to sport events. Understanding sport events as a multiphase experienc...
Design and Analysis of Multiphase DC-DC Converters with Coupled Inductors. (May 2007) Meng Shi, B.Eng., Shanghai Jiao Tong University, China Chair of Advisory Committee: Dr. Prasad Enjeti In this thesis, coupled inductors have been applied to multiphase DC-DC converters. Detailed analysis has been done to investigate the benefits of directly coupled inductors and inversely coupled inductors, co...
