Micromixers — a review
This review reports the progress on the recent development of micromixers. The review first presents the different micromixer types and designs. Micromixers in this review are categorized as passive micromixers and active micromixers. Due to the simple fabrication technology and the easy implementation in a complex microfluidic system, passive micromixers will be the focus of this review. Next,...
متن کاملModelling Annular Micromixers
Magnetohydrodynamic mixing of two fluids in an annular microchannel is modelled as a twodimensional, laminar, convection-diffusion problem, and examined using asymptotic analysis and numerical simulation. The time T required for mixing of a plug of solute depends on the Peclét number Pe, and on the geometry of the annulus. Three scaling regimes are identified: purely diffusive, Taylordispersive...

امروزه تصحیح همکلاسی در کلاسهای نگارش یکی از اجزاء لاینفک کلاسهای دانش آموز محور است. تاثیرات مفید تصحیح همکلاسی بر زبان آموزان، معلمان را متقاعد کرده است که علیرغم صرف زمان، انرژی و توان بسیار، از این شیوه ی آموزشی در کلاسهای آموزش نگارش بهره بگیرند. تحقیق حاضر بر آن است تا با مقایسه دو گروه از یادگیرندگان زبان انگلیسی، تاثیر تصحیح همکلاسی را بر توانایی نوشتاری آنها نشان دهد. 122 خانم زبان آمو...
15 صفحه اولPrint-and-peel fabricated passive micromixers.
Advection driven mixing is essential for microfluidics and poses challenges to the design of microdevices. Force transducers or complex channel configurations provide means for, respectively, active or passive disrupting of laminar flows and for homogenizing the composing fluids. Print-and-peel (PAP) is a nonlithographic fabrication technique that involves direct printing of masters for molding...
متن کاملGeometric effects on fluid mixing in passive grooved micromixers.
The effects of geometric parameters on the mixing performance of a staggered herringbone mixer (SHM) with patterned grooves are numerically investigated. Combining use of the software package CFD-ACE+ and the Taguchi method provides a powerful and systematic approach for research on microfluidics. An orthogonal array L9(3(4)) is established for parameters introduced by the groove geometry; in t...
