我们通过三维（3D）打印提出了一种微型微泡发生器，有望用于气液化学反应。我们基于文丘里通道结构进行设计，通过湍流相互作用实现连续的气体分散，并使用3D打印制造它，因为它具有高设计灵活性和快速制造速度。通过水和氮气实验，定量讨论了形成的微泡特性对操作条件和几何参数的依赖关系。特别地，提出了子气泡Sauter平均直径的预测模型，以帮助选择合适的操作和设计参数，以达到理想的微气泡水平。为了进一步提高性能，我们探索了串联和并行文丘里结构，发现基于并行的装配性能明显更好。因此，我们证明了3D打印文丘里微泡发生器在流动化学领域实现气液反应具有很高的潜力。
We present a miniaturized microbubble generator via three-dimensional (3D) printing for potential use in gas-liquid chemical reactions. We design it based on venturi channel structures to enable continuous gas dispersion by turbulent interactions and fabricate it using 3D printing for its high design flexibility and fast manufacturing speed. By experiments using water and nitrogen, we discuss quantitatively the dependence of the formed microbubble characteristics on operating conditions and geometric parameters. In particular, predictive models of Sauter mean diameter of daughter bubbles are proposed to help select proper operating and design parameters in order to achieve the desired level of microbubbles. To further improve the performance, we explore series- and parallel-venturi configurations and find that the parallel-based assembly performs significantly better. Therefore, we prove that the 3D printed venturi microbubble generator has high potential for the flow chemistry community to implement gas-liquid reactions.
