Experimental comparative mixing performance of passive micromixers with H-shaped sub-channels

Experimental comparative mixing performance of passive micromixers with H-shaped sub-channels

This paper presents a new type of passive microfluidic mixer called the “H-micromixer”. This type of passive micromixer is based on the splitting and recombination (SAR) process, meaning that the two fluids to be mixed are split and recombined to optimize the diffusion process. The paper also descri...

Zusammenfassung:This paper presents a new type of passive microfluidic mixer called the “H-micromixer”. This type of passive micromixer is based on the splitting and recombination (SAR) process, meaning that the two fluids to be mixed are split and recombined to optimize the diffusion process. The paper also describes an experimental investigation of the mixing process in three different geometries: T-micromixer, O-micromixer and H-micromixer. The laminar flow regime (0.08
