The theoretical performance of a planar microscale ion generation device is analyzed using the direct simulation Monte Carlo (DSMC) technique. The discrete motion and interactions of electrons and ions are modeled for atmospheric air as represented by N2 and O2. The ionization threshold of the device in air is found to be 70 V because of the effects of molecular excitations that reduce the ener...

Microfluidic flow based multiplexed devices have gained significant promise in detecting biomarkers in complex biological samples. However, to fully exploit their use in bioanalysis, issues such as (i) low sensitivity and (ii) high levels of nonspecific adsorption of non-target species have to be overcome. Herein, we describe a new multiplexed device for the sensitive detection of multiple prot...

in this paper, the effect of electric field on two-dimensional low reynolds air flow around an airfoil and variation of the forces acting on the airfoil is numerically investigated. the electric current and poisson’s equations are solved and the outcome is considered as a source term in the momentum equations. the energy equation is not considered due to its weak effect on the phenomena. the fi...

Abstract Electrohydrodynamics is crucial in many nanofluidic and biotechnological applications. In such small scales, the complexity due to coupling of fluid dynamics with ions increased by relevance thermal fluctuations. Here, we present a mesoscale method based on Dissipative Particle Dynamics (DPD) model fluid. Two scalar quantities, corresponding number positive negative carried each DPD pa...

The electro-diffusion model, which arises in electrohydrodynamics, is a coupling between the Nernst-Planck-Poisson system and the incompressible Navier-Stokes equations. For the generally smooth doping profile, the quasineutral limit (zero-Debye-length limit) is justified rigorously in Sobolev norm uniformly in time. The proof is based on the elaborate energy analysis and the key point is to es...

We study numerically a sequence of eddies in two-dimensional electrohydrodynamics (EHD) flows dielectric liquid, driven by an electric potential difference between hyperbolic blade electrode and flat plate (or the blade–plate configuration). The electrically flow impinges on to generate vortices, which resemble Moffatt (Moffatt, J. Fluid Mech. , vol. 18, 1964, pp. 1–18). Such phenomenon EHD was...
