the problem of steady magnetohydrodynamic boundary layer flow of an electrically conducting nanofluid due to an exponentially permeable stretching sheet with heat source/sink in presence of thermal radiation is numerically investigated. the effect of transverse brownian motion and thermophoresis on heat transfer and nano particle volume fraction considered. the governing partial differential eq...

We have investigated the rate sensitivity of flow stress and the extent of strengthening in polycrystalline copper containing different volume fractions of nano-sized twins, but having the same average grain size. The specimens were produced by pulsed electrodeposition, wherein the concentration of twins was varied systematically by varying the processing parameters. Depth-sensing instrumented ...

Recent advances in microfluidics and microfabrication techniques have led to a variety of portable and inexpensive lab-on-a-chip devices to make quantitative assays of microscale and nanoscale bioparticles. Among them, electrical impedance flow cytometers have become an indispensable tool in clinical and research laboratories for analysis of micro/nano bio-objects. Because of their simplicity a...

A submicroscale flow sensor has been developed that consists of a suspended hot film and carbon nanotube (CNT) fins. Flow measurement experiments, together with a theoretical model, revealed the advantages of the use of CNT fins. The suspended metal film reduces heat loss and the CNT fins enhance the heat transfer to the fluid flow. Herein, the working principle of the CNT fins is presented in ...

In this study first and second law analyses of non-Newtonian nano-fluid flow through an annular cylinder filled with water- CMC/TiO2 by considering temperature jump slip velocity were investigated numerically. The single-phase was developed for heat transfer flow. impact Reynolds number, nano-particles volume fraction, jump, on Nusselt numbers entropy generation evaluated the findings discussed...

The electroviscous effect has been widely studied to investigate the effect of surface charge-induced electric double layers (EDL) on the pressure-driven flow in a micro/nano channel. EDL has been reported to reduce the velocity of fluid flow and increase the fluid drag. Nevertheless, the study on the combined effect of EDL with large zeta potential up to several hundred millivolts and surface ...
