Investigation of additives nanoparticles and sphere barriers effects on the fluid flow inside a nanochannel impressed by an extrinsic electric field: A molecular dynamics simulation

Abstract

In this paper, MD technique was employed to predict the atomic barrier impact on H2O/Copper nanofluid dynamic manner in existence of outer electric subject. To examine the H2O/Copper nanofluid flow, the Copper nanochannel with sphere barriers was simulated. In these MD simulations, the interactions between atoms of atomic structures were explained via Lenard-Jones force fields and Embedded Atom Model. To examine the atomic manner of these structures, physical specification like density, velocity and temperature profiles of H2O/Copper nanofluid reported. MD simulation outcomes display that, these physical specification of H2O/Copper nanofluid within non-optimal nanochannel effected by atomic barriers size transformations. Further, the effects of external electric field magnitude and frequencies variation on dynamical manner of H2O/Cu calculated. Numerically, it is calculated that, highest rate of temp., velocity and density profiles reach to 0.123 atom/Å3, 0.986 Å/ps, and 513 K rates which these theatrical reports can be significant for actual application of nanofluid structures.
