Cadmium Sulfide Nanoparticle Synthesis Using Oscillatory Flow Mixing
ASME 2011 International Manufacturing Science and Engineering Conference, Volume 2, 2011Microchannel mixers enable faster mixing times compared with batch stir mixing leading to the promise of higher throughput, better yields and less solvent usage for the solution-phase reactive precipitation of inorganic nanoparticles. However, reliance on diffusive transport for subsecond mixing requires channel dimensions in the tens of micrometers ...

Supersonic mixing enhanced by cavity-induced three-dimensional oscillatory flow
Experiments in Fluids, 2014In this study, a novel wall-mounted cavity having a three-dimensional shape is proposed for enhancing supersonic mixing. This device induces an oscillatory secondary flow that effectively enhances mixing. To demonstrate the device performance, we experimentally compare supersonic mixing fields in three ducts without any devices, with a rectangular ...

A Mixing-Based Design Methodology for Continuous Oscillatory Flow Reactors
Chemical Engineering Research and Design, 2002Oscillatory flow reactors (OFR) have been actively developed over the last fifteen years at a number of UK universities, including the department of Chemical Engineering, University of Cambridge. OFRs exploit the uniform and efficient vortex mixing that can be achieved when an oscillatory fluid motion interacts with orifice plate baffles in a tube. One

Chaotic mixing in microfluidic devices driven by oscillatory cross flow
Physics of Fluids, 2008The kinematics of oscillatory cross flow has been studied numerically as a means for generating chaotic mixing in microfluidic devices for both confined and continuous throughput flow configurations. The flow is analyzed using numerical simulation of the unsteady Navier–Stokes equations combined with tracking of single and multispecies passive tracer ...

Mixing induced by oscillatory stratified flow past a right-circular cylinder
Journal of Fluid Mechanics, 1995A series of laboratory experiments was performed to investigate the overall mixing characteristics of oscillatory stratified flow past an isolated topography. The experiments were conducted by oscillating a right-circular cylinder in an otherwise quiescent linearly stratified fluid contained in a rectangular basin.

Transport processes of uniform and mixed sands in oscillatory sheet flow
Coastal Engineering, 2005New experiments were carried out in the Large Oscillating Water Tunnel of WL|Delft Hydraulics (scale 1:1) using asymmetric 2nd-order Stokes waves. The main aim was to gain a better understanding of size-selective sediment transport processes under oscillatory plane-bed/sheet-flow conditions. The new data show that for uniform sand sizes between 0.2 <

Effect of chaotic advection generated by oscillatory flow on mixing-induced precipitation
2022<p>Chaotic advection can be created by engineered sequence of extraction and injection of groundwater in aquifers and by creating an engineered oscillatory flow. It has been used in a wide range of applications, including enhancement of degradation during aquifer remediation, in-situ leaching of metals to enhance mining recovery, and ...

A Numerical Scheme for Fractional Mixed Convection Flow Over Flat and Oscillatory Plates
Journal of Computational and Nonlinear Dynamics, 2022Abstract A fractional scheme is proposed to solve time-fractional partial differential equations. According to the considered fractional Taylor series, the scheme is compact in space and provides fourth-order accuracy in space and second-order accuracy in fractional time.

Enhanced Mixing and Plume Containment in Porous Media under Time-Dependent Oscillatory Flow
Environmental Science & Technology, 2009Solute transport experiments were conducted in a decimeter scale flow cell packed with sand to study the potential for enhanced mixing of solutes in porous media and improved containment of injected plumes under multiple pumping-well driven, time-dependent oscillatory flow with respect to constant flow. Real-time imaging of the colorimetric reaction of
