Microfluidic mixing in a Y-junction open channel

effects of open-channel geometry on flow pattern in a 90° junction

open-channel junctions have a broad application in civil and environmental engineering. formation of a low-pressure zone with recirculating flow (high sedimentation) accompanied by a high-velocity zone (high erosion) is the most characteristic feature of flow in junctions. a large number of researches have been performed to study the complexity of the flow in junctions in open-channel flows. in...

Microfluidic Mixing: A Review

The aim of microfluidic mixing is to achieve a thorough and rapid mixing of multiple samples in microscale devices. In such devices, sample mixing is essentially achieved by enhancing the diffusion effect between the different species flows. Broadly speaking, microfluidic mixing schemes can be categorized as either "active", where an external energy force is applied to perturb the sample specie...

Mixing enhancement in a microfluidic device

Microfluidic Mixing CNF Project

Microfluidic systems present advantages and challenges relative to larger systems for performing chemical processes. They facilitate manipulation and analysis of small sample volumes and process parallelization within a small footprint. However, they generally suffer from inefficient mixing and low rates of interfacial mass transfer, due to the laminar flow and the long diffusive mixing times c...

Rapid microfluidic mixing.

A preformed T-microchannel imprinted in polycarbonate was postmodified with a pulsed UV excimer laser (KrF, 248 nm) to create a series of slanted wells at the junction. The presence of the wells leads to a high degree of lateral transport within the channel and rapid mixing of two confluent streams undergoing electroosmotic flow. Several mixer designs were fabricated and investigated. All desig...
