Electrokinetic Flow Diagnostics
S. Devasenathipathy and J.G. Santiago The advent of microfabricated chemical analysis systems has led to a growing interest in microfabricated fluidic systems with characteristic scales in the range of a micron to a millimeter. A motivation to integrate components in a manner analogous to modern microelectronics is coupled with a potential for achieving massively parallel functions, and the fie...
متن کاملTwo-fluid Electrokinetic Flow in a Circular Microchannel (RESEARCH NOTE)
The two-fluid flow is produced by the combined effects of electroosmotic force in a conducting liquid and pressure gradient force in a non-conducting liquid. The Poisson-Boltzmann and Navier-Stokes equations are solved analytically; and the effects of governing parameters are examined. Poiseuille number increases with increasing the parameters involved. In the absence of pressure gradient, the ...
متن کاملElectrokinetic Flow and Dispersion in Capillary Electrophoresis
Electrophoretic separation of a mixture of chemical species is a fundamental technique of great usefulness in biology, health care, and forensics. In capillary electrophoresis (which has evolved from its predecessor, slab-gel electrophoresis), the sample migrates through a single microcapillary instead of through the network of pores in a gel. A fundamental design problem is to minimize dispers...
متن کاملIon exclusion and electrokinetic effects resulting from electro-osmotic flow of salt solutions in charged silica nanopores.
Silica nanopores are the focus of significant scientific interest due to their potential in a wide variety of applications including desalination membranes. In this paper, the results of extensive all-atom molecular dynamics simulations of the electro-osmotic flow of 0.5 M monovalent (NaCl) and divalent (CaCl(2)) ionic solutions through cylindrical charged silica nanopores are presented. The si...
متن کاملElectrokinetic Flotation of Paint Solids in a Continuous Flow Tank
The treatment of water from paint spray booths in automobile assembly plants typically involves applications of large quantity of chemicals as coagulants and flocculants. Suspended paint solids are brought to water surface in sludge pits after these chemicals are added. The suspended paint particles are then mechanically collected and removed as sludge for further treatment and disposal. There ...
