Abstract

The invention provides a distorted arc-shaped micro mixer based on an enhanced secondary flow effect. The micro mixer comprises a plurality of inlets, a mixing pipeline, an arc-shaped bend hybrid matrix and an outlet, wherein the inlets are communicated with one end of the arc-shaped bend hybrid matrix through the mixing pipeline, the other end of the arc-shaped bend hybrid matrix is communicated with the outlet, and the arc-shaped bend hybrid matrix comprises a plurality of arc-shaped bend mixing units which are sequentially communicated. Compared with a common S-type mixing pipeline, the mixing speed of the mixer is increased in a nonlinear mode along with mixing length increase.

Description

technical field [0001] The invention relates to a micro-mixer chip, in particular to a twisted arc-shaped micro-mixer based on enhancing the secondary flow effect of a bend. Background technique [0002] Micromixers are devices used to mix small volumes of fluid flowing in very narrow channels. Micromixers are essential in many microfluidic systems aimed at biochemical analysis, drug delivery, and nucleic acid serialization or synthesis. Biological processes such as cell activation, enzyme reactions, and protein folding often involve reactions that require starting with a mixture of reactants. Mixing is also necessary in multiple microfabricated chemical systems for complex chemical synthesis. See "Passive Mixing ina Three-Dimensional Serpentine Microchannel," R.H. Liu, M.A. Stremler, K.V. Sharp, Journal of Microelectromechanical System, Vol.9, No.1, June 2000. [0003] The phenomenon known as laminar flow exhibits very different properties when fluids flow in channels ap...
