Unfortunately, the flow velocity is inversely proportional to the square of channel dimensions, so this pump scales in the wrong direction for microfluidics. A magnetohydrodynamic pump for pumping a fluid. Magnetohydrodynamic-based Laboratories on a Chip key capability of MHD microfluidics which was demonstrated in Phase I is the ability to pump fluids along closed. The magnetohydrodynamic (MHD) pump has attracted a lot of attention in today's technology especially for biotechnology and drug delivery applications. The basic theoretical analyses were presented and the next. Magneto-hydrodynamic (MHD) principle is an important interdisciplinary field. Nash and Ingrid Fritsch University of Arkansas Department of Chemistry and Biochemistry Fayetteville, AR 72701 The miniaturization of analytical techniques has been the trend during the last couple of decades as. A liquid-metal based spiral magnetohydrodynamic (MHD) micropump is proposed in this work. I'm trying to modeling a MHD DC pump (magneto hydrodynamic conduction pump) I founded papers who discuss this model, but i´d like to simulate in comsol. capillary pump/valve consisting of a bi-phase slug confined in a non-uniform conduit is described. A magnetohydrodynamic pump for pumping a fluid. Such a feature form the basis for the classification provided in the USA Standard (ASTM 17389-72). Magnetohydrodynamics (MHD) offers an. A new approximate solution for the velocity profile of steady incompressible magnetohydrodynamic (MHD) flows in a rectangular microchannel driven by the Lorentz force is proposed. The pump includes a microfluidic channel for channeling the fluid, a MHD electrode/magnet system operatively connected to the microfluidic channel, and a system for promoting flow of the fluid in one direction in the microfluidic channel.

The application of this pump for the study of biological samples in a miniaturized total analysis system (mu TAS) with integrated NMR detection is foreseen. Classification of pumps USA Standard Devices for pressure transfer of liquids are divided into species and varieties on various grounds, such as the principle of action and design.
