Dean vortex membrane microfiltration and diafiltration of rBDNF E. coli inclusion bodies

, 2002
Cross-flow microfiltration (CMF) and diafiltration were used to concentrate and purify recombinant Brain-Derived Neutrophic Factor (rBDNF) inclusion bodies from an E. coli cell suspension and a homogenized E.

Sinusoidal Microchannel with Descending Curves for Varicose Veins Implantation

Micromachines, 2018
Approximately 26% of adult people, mostly females, are affected by varicose veins in old age. It is a common reason for distress, loss of efficiency, and worsening living conditions.

Large eddy simulation of turbulent vortices and mixing layers

, 2008
In this dissertation large-eddy simulation(LES) is used to study the transitional and turbulent structures of vortices and free shear layers. The recently developed dynamic model and the basic Smagorinsky model are utilized to model the subgrid-scale(SGS)

Investigation of Secondary (Dean) Flows in Curved Microchannels and Application to Microparticle Sample Preparation [PDF]

, 2018
Exchanging the solution of microparticles from a complex source fluid to a target clean buffer is important for sample preparation in portable microfluidic and point-of-care diagnostic devices. Current portable solution exchange methods are often limited

Computation of Reynolds stresses in axisymmetric vortices and jets using a second order closure model

, 2009
Donaldson's single-point second-order model [13] is used to close the Reynolds stress transport equations in cylindrical coordinates. A reduced set of equations are then solved for the decay of axisymmetric vortices and jets.

Mixing enhancement with generation of effective secondary flow parallel to fluid interface in three-dimensional serpentine channel

Results in Engineering
Mixing efficiency is an important factor for various miniaturized systems that handle small volumes of samples. Serpentine channels, which are commonly employed for passive mixing, have been modified and designed based on three-dimensional (3D ...
