Outline of Final Research Achievements	In this research project, we added Leidenfrost droplets on a heated plate, which became a new international joint research project with National Taiwan University during this period, to the three initially established complex fluids: 1) strongly non-Newtonian fluid, 2) multiphase fluid with a highly concentrated dispersed phase, and 3) viscoelastic fluid, and clarified how each complex fluid affects vortex generation, extinction, size, shape, and controllability of dynamic properties. In addition to National Taiwan University and City University of Hong Kong, which were originally envisioned through this research, collaborations with RMIT University (Australia), CSIRO (Australia), and the University of Liverpool (UK) were also established.

Academic Significance and Societal Importance of the Research Achievements	研究に参画した若手研究者が、本研究課題を通じて、当初の共同研究先であった国立台湾大学及び香港城市大学に加え、独自で国際研究ネットワークを広げ、新たな共同研究を開始したことから、本研究プロジェクトの若手研究者育成への寄与は非常に大きい。さらに、本研究課題だけではなく、新たな共同研究テーマを相手機関と立ち上げ、国際共著論文を執筆するなど、国際共同研究促進にも大きく寄与したと考えられる。
