摘要
In this article dedicated to micromixing, we concentrate here on a particular micromixer - the 'cross-channel micromixer'. This mixer exploits an oscillatory perturbation to induce chaotic trajectories, favoring mixing. We present here theory, numerical simulations and experiments performed on this system.
