Chaotic Mixers: Efficient Fluid Mixing in Microreactors

This lecture explores chaotic mixers in microreactors, focusing on the generation of complicated fluid trajectories through chaotic advection. It covers the principles of mixing by diffusion and advection, the design of micromixers, and the advantages of segmented-flow microreactors. Examples of chaotic mixers, such as the zigzag channel micromixer and the Meander micromixer, are discussed to illustrate the efficient mixing processes. The lecture also delves into the characteristics of different flow regimes for gas-liquid and liquid-liquid systems, emphasizing the advantages of segmented-flow microreactors in enhancing mass transfer rates.
