Fast mixing using the Shear Superposition Micromixer

摘要

We are presenting experimental studies and numerical simulations to analyze an actively controlled mixer. The current design of the micromixer is called "shear superposition micromixer". This micromixer consists of a main mixing channel where unmixed fluids are perturbed by jet flows emanating from series of transverse channels. Mixing of two fluids is achieved using the kinetic of the side jet flows. We quantify, numerically and experimentally, the degree of mixing achieved using the Mixing Variance Coefficient (MVC). We present some flow properties. Single channel mixing can be very good when amplitude and frequency are chosen carefully.
