In the current research, numerical analysis was used to investigate flow behavior through axial jet-pump with various mixing chamber configurations (straight pipe and straight pipe-diffuser-straight pipe) in presence of inlet swirling its influence on pump performance. The effects introducing suction motive line, are numerically investigated. optimum swirl angle is found be 45o which yields max...

The current study numerically investigates an active mixing enhancement technique for a supersonic ejector with constant area chamber operating under the critical regime. Streamwise control jet injections are alternatively pulsed at top and bottom sides of entrance. induced oscillation primary enhances bulk between secondary streams. stream penetrates core flow much upstream strategy compared t...

We report on a light-actuated, droplet based microfluidic platform enabling two-dimensional (2D) droplet manipulation on an open chamber with a single-side, featureless photoconductive surface. The droplet actuation mechanism is based on recently demonstrated floating electrode optoelectronic tweezers (FEOET), which enable light-induced dielectrophoretic forces to manipulate aqueous droplets im...

Homogeneous matrices of calcium oxide (CaO) were prepared by mixing this material with polyethylene glycol (PEG) acting as malleable inert support in order to obtain processable composites. Preliminary tests were carried out to assess the best concentration of CaO in the composite, individuated in the CaO/PEG weight ratio of 1/4. Experimental data highlighted that the composite was able to sele...

This paper reports a technique for temperature-induced merging of droplets in a microchannel. The multiphase system consists of water droplet and oil as the dispersed phase and the carrying continuous phase. A resistive heater provides heating in a rectangular merging chamber. The temperature of the chamber is controlled by the voltage applied to the heater. The merging process of two neighbori...

We discuss the mechanisms by which bulk electrohydrodynamic air thrust or ionic wind generated above and directed towards the surface of a microfluidic chamber by a sharp electrode tip can give rise to surface or bulk liquid recirculation in the chamber and demonstrate various ways in which the phenomenon can be exploited for microfluidic mixing and particle trapping. In the latter, micropartic...

First published April 10, 2013; doi:10.1152/jn.01039.2012.—There are currently no practical systems that allow extended regions ( 5 mm) of a tissue slice in vitro to be exposed, in isolation, to changes in ionic conditions or to pharmacological manipulatio...

CI engines are widely used in stationary as well as mobile applications. Stationary applications include typical gen-set, etc. and mobile applications include heavy automobiles, forestry equipments, etc. as well as other applications in day-to-day life. Since the turbulence is necessary for better mixing and the fact that it can be controlled by shape of the combustion chamber, makes this revie...
