Mixing Performance of the Modified Tesla Micromixer with Tip Clearance

open access: yesMicromachines, 2022
A passive micromixer based on the modified Tesla mixing unit was designed by embedding tip clearance above the wedge-shape divider, and its mixing performance was simulated over a wider range of the Reynolds numbers from 0.1 to 80. The mixing performance

Reconfigurable metamaterial structure for 5G beam tilting antenna applications [PDF]

open access: yes, 2020
In this paper, we propose a metamaterial (MTM) structure with a reconfigurable property designed to operate at the millimetre-wave (mm-wave) spectrum. Four switches are used to achieve the reconfigurable property of the MTM with two configurations. These

Photoresponsive Passive Micromixers Based on Spiropyran Size‐Tunable Hydrogels

open access: yesMacromolecular Rapid Communications, 2017
AbstractMicrofluidic devices allow the manipulation of fluids down to the micrometer scale and are receiving a lot of attention for applications where low volumes and high throughputs are required. In these micro channels, laminar flow usually dominates, which requires long residence times of the fluids, limiting the flow speed and throughput.

A fast passive and planar liquid sample micromixer

open access: yesLab Chip, 2004
A novel microdevice for passively mixing liquid samples based on surface tension and a geometrical mixing chamber is presented. Due to the laminar flow regime on the microscale, mixing becomes difficult if not impossible. We present a micromixer where a constantly changing time dependent flow pattern inside a two sample liquid plug is created as the ...
