| Outline of Final Research Achievements |
The objective of this research project was to systematize "Vortex Dynamics" from a chemical engineering perspective, focusing on the functional structure of vortices in terms of solid accumulation, mixing/reaction, classification, and transport. In our research on Taylor vortex flow, we first discovered a gas-liquid slug flow in which the gas and liquid phases alternate in a cylindrical system with a narrow gap between the inner and outer cylinders, and we clarified that the axial diffusion in this flow system is extremely small, which dramatically enhances the performance as a tube-type reaction device. We also obtained a patent jointly with a company for a chemical reaction apparatus and operating method that applies this flow. The research results obtained this research project were summarized in two review papers and published in an academic journal and an academic book, respectively.
