Effects of Magnetically Induced Micro-mixing on Nanofiltration Performance
… the movement of the polymer chains acts as micro-mixer leading to the suppression of concentration polarization and improved filtration performance. NF270 is one of the most commonly used NF membranes for removing low molecular weight species and di- and trivalent ions from the feed …

Precipitation of ultrafine particles using liquid antisolvent with concentric ultrasonic nozzle and subcritical CO2
… interfacial surface area. This work focuses on micronization of class ii drug Griseofulvin which is poorly water soluble. Two processes namely, liquid antisolvent precipitation using ultrasonic nozzle and other process using subcritical CO_2 have been used to produce ultrafine particles of this …

A PDMS Sample Pretreatment Device for the Optimization of Electrokinetic Manipulations of Blood Serum
… blood serum and adaption of that protocol to a microfluidic environment in order to optimize key sample characteristics, namely pH, conductivity, and viscosity, to enable on-chip electrokinetic separations. The two major parts of this project include (1) designing a pretreatment protocol to …

Turbulent mixing and chemical reaction in baffled stirred tank reactors : a comparison between experiments and a novel micromixing-based computational fluid dynamics model
… approach based on the use of CFD coupled with micromixing models was used to predict the behavior of a multiple, competitive reaction system in cylindrical stirred tank reactors fitted with a variety of agitators. In particular, the following fast parallel competing reactions scheme (Bourne and …

Application of the Vortex Fluid Device (VFD) in Polysulfone Synthesis and Ultra-filtration Membrane Fabrication for water treatment purposes
… from a combination of different effects (e.g., micro-mixing, viscous drag, microfluidic flow, enhanced mass transfer) all resulting in faster, greener, and more efficient and better controlled chemical reactions. The main aims of this project are: (i) to investigate the utility of VFD processing …

Modelling of Spray Combustion with Doubly Conditional Moment Closure
… by a strong coupling of evaporation, mixing and chemical reaction. This leads to a wide spectrum of combustion regimes, where self-propagating premixed flames and diffusion-controlled non-premixed flames may occur simultaneously within the same flame. The physical processes involved in …
