We present a novel electroosmotic micromixer that consists of arrays of direct current (DC) asymmetric electrode and asymmetric lateral structures. By embedding asymmetric electrode arrays on the top and bottom walls of a rectangular microchannel appropriately, the flow perturbations and vortexes can be induced when a DC electric field is imposed. An efficient lateral structure is then sequenti...

We derive an analytic expression for the mechanical pressure of a generic one-dimensional model confined active Brownian particles (ABPs) that is valid all values Peclet number Pe and confining scenarios. Our reproduces known scaling bulk with Pe^2 while in strong confinement scales Pe. results are very well reproduced by simulations ABPs 2D. use formula to calculate both work performed engine ...

The paper investigates the linear growth of mixing zone, in a pessimistic scenario, during polymer slug injection into water reservoir. velocities front and boundaries zone are numerically analytically studied as key parameters characterizing miscible displacement. Using two different numerical methods (finite volumes finite elements), impact size, reservoir dimensions, Peclet number, viscosity...

The anisotropic transfer of dielectric particles by a uniform electric field in nonuniformly heated fluid is modeled. transport anisotropy determined the mechanism interaction between whose permittivity depends on temperature. temperature distribution and their thermal diffusivity does not depend motion fluid, thus corresponding to small Peclet numbers. flow considered approximation Reynolds du...

The present paper aims at investigating the applicability of hybrid cells in the series model for pollution transport inside the layered porous media. For this purpose, four layers of rock material have fallen inside the experimental flume, with eight sensors installed longitudinally inside the media to obtain experimental BTCs. In order to measure time parameters of the model, named , two diff...

In the present paper, fluid flow and heat transfer of a nanofluid are numerically investigated. More specifically, reference is made to nanofluid, described by means Buongiorno’s model, subjected Couette flow. The considered domain consists channel that displays cavity shortly after inlet section. transport model for mass conservation, momentum, nanoparticles equation, written in dimensionless ...

In this paper conjugated heat transfer in thermal entrance region through the sinusoidal wavy channel has been investigated. The fluid flow is assumed to be laminar, steady state, incompressible, and hydrodynamically fully developed. A constant heat flux is assumed to be applied on the outer edge of the channel wall. In this study the governing equations including continuity, momentum and energ...
