Interaction of Electroosmotic Flow on Isotachophoretic Transport of Ions
A numerical study on the influence of electroosmotic flow on analyte preconcentration by isotachophoresis ( ITP) is made. We consider that the double layer induced electroosmotic flow ( EOF) counterbalance the electrophoretic velocity and a stationary ITP stacked zones results. We solve the Navier-Stokes equations coupled with the Nernst-Planck equations to determine the local convective veloci...
متن کاملمطالعه تجربی شعله دیفیوژن counter-flow
در این تحقیق به مطالعه شعله پس اختلاط counterflow در حالت جریان آرام پرداخته شده است. تحقیقات صورت گرفته در این پروژه را می توان به دو دسته تجربی و عددی تقسیم کرد. در قسمت تجربی، جهت انجام آزمایشات، مشعل counterflowطراحی و ساخته شده است. مشعل طراحی شده از دو تکه تشکیل شده که بصورت روبروی هم قرا گرفته اند. هر کدام از آنها شامل دو لوله هم محور با قطرهای مختلف می باشند که فاصله بین دو تکه را می تو...
15 صفحه اولElectro-osmotic flow of a model electrolyte.
Electro-osmotic flow is studied by nonequilibrium molecular dynamics simulations in a model system chosen to elucidate various factors affecting the velocity profile and facilitate comparison with existing continuum theories. The model system consists of spherical ions and solvent, with stationary, uniformly charged walls that make a channel with a height of 20 particle diameters. We find that ...
متن کاملMagnetohydrodynamic flow of RedOx electrolyte
Magnetohydrodynamic MHD flow of a RedOx electrolyte in a straight conduit is investigated theoretically. Inert electrodes are deposited along segments of the opposing walls of a straight conduit that is filled with a RedOx electrolyte solution. The conduit is positioned in a uniform magnetic field. When a potential difference is applied across the opposing electrodes, the resulting current inte...
متن کاملA redox-flow battery with an alloxazine-based organic electrolyte
Redox-flow batteries (RFBs) can store large amounts of electrical energy from variable sources, such as solar and wind. Recently, redox-active organic molecules in aqueous RFBs have drawn substantial attention due to their rapid kinetics and low membrane crossover rates. Drawing inspiration from nature, here we report a high-performance aqueous RFB utilizing an organic redox compound, alloxazin...
