Abstract
Micromixers represent microchannel devices that promote effective fluid integration within a constrained spatial domain and a specified flow pathway. The mechanism of induced-charge electroosmosis has garnered substantial attention from the microfluidics scholarly community over the past decade. In this study, an electroosmotically actuated micromixer amalgamates two disparate fluids that enter through individual inlets into a unified channel measuring 15 μm in width and 80 μm in length, respectively. A sinusoidal electric potential, with a peak value of 0.1 V at a frequency of 8 Hz, is applied across the electrodes. To enhance the operational efficacy of the micromixer, 45 uniform circular barriers are integrated within the microchannel. According to the simulation outcomes, the micromixer attains an exemplary mixing efficiency nearing 0.97 and exhibits promising potential applications across a diverse array of fields, including biochemistry and biomedical sciences.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
