Micromixer is widely used in biomedical diagnosis and micro/nanomanufacturing. Mixing in micromixer plays a key role in chemical reactions, homogenization, and emulsification.
To date, many types of mixers for use in microfluidic device have been developed and improved. Staggered herringbone micromixers (SHMs) which induces chaotic advection because of the asymmetric geometry, is widely used. However, the disadvantage of the Staggered herringbone micromixer is that it is complicated and expensive process in micro scale.
To address this, toroidal mixer design (TrM) has been developed and this design offers comparable mixing efficiencies under laminar flow at high fluid speeds.
This induces chaotic advection through increasing the number of vortices and centrifugal forces created between the columns within the cartridge, allowing for improved mixing and also allowing for higher throughput
Here, we modified the channel width and neck angle of TrM design to find the optimization condition.
