Abstract

The authors propose a passive micro mixer with the Split-and-Recombine (SAR) structure. Two mixing fluids become the multilayer condition by the SAR Structure. Then, the contact area increases, the thicknesses of layer decreases, and the mixing can be accelerated. In this method, it is important to put the thickness of layers into the multilayer condition of even width to mix more efficiently. Result of the numerical simulation in a SAR structure shows that the position of the contact surfaces between two fluids can be controlled by changing the channel configuration of the split part. And also result of quantitatively evaluating mixing efficiency in the Cross SAR structure shows that an efficient mixing is possible, and a great mixing acceleration is obtained. It is conforms that the method of this mixing acceleration is very effective.
