Studying the Quality of Micromixing in a Single-Stage Microreactor with Intensively Swirled Flows

The work considers the results of experimental and numerical study on the hydrodynamic characteristics of a jet vortex reactor mikro-VSA-1, for which one of the application fields is the synthesis of oxide materials (e.g., perovskite-like material for solar panels). The energy-dissipation rate and micromixing quality are studied (by the iodide–iodate method) for various methods of supplying micro-VSA-1 and T-shaped millireactors with solutions. Numerical modeling reveals the volumes with the highest energy-dissipation rate. The quality of micromixing in the micro-VSA-1 is shown to be much higher than in the T-shaped millireactor, due to, among other things, the fact that the zone with the highest energy-dissipation rate is localized near the neck of the micro-VSA-1.
