The environment has recently been damaged by human activity. In our laboratory, we study two technologies: environment restoration technology and the technology for the reduction of environmental impact, by means of fluid engineering. Our main focus is to develop such technologies by using a large quantity of micro scale bubbles. This technology makes it possible to efficiently dissolve oxygen in water in the environment on a massive scale. Dissolved oxygen restores the ecological systems and material cycle systems, providing the water environment strong environment-restoration ability. Our field experiments are carried out at testing sites such as lakes and water-storage dams, in cooperation with the local government authority. To support and verify our fieldwork, we perform experiments in our laboratory on campus, which attempt to predict the process of water environment restoration by simulating heat, fluid flow, diffusion, and chemical reaction in the environment.
