Development of Transdisciplinary Integrated Multiscale Multiphase Flow Energy System

Our laboratory is focusing in the development of innovative multiphase fluid dynamic methods based on the multiscale integration of massively parallel supercomputing and advanced measurements, and research related to creation of environmentally conscious energy systems. Furthermore, we promote basic research for the creation of risk management science and associated new multiphase flow system directly linked to sustainable energy represented by a high-density hydrogen storage technology.

Particularly, we are focusing in different field integration research and development such as creation of environmentally conscious type nano-cleaning technology using reactive multiphase fluid that is a thoroughly chemical-free, pure water free, dry type semiconductor wafer cleaning system using cryogenic micro-nano-solid high-speed spray flow, and also focusing on removal-reusing technology for solar cells and ITO membranes for conducting organic polymer (including indium oxide tin). We also performed computational study of multiple bubbles behavior in megasonic field to clarify the mechanism of particle removal by megasonic cleaning.

Furthermore, aiming to contribute disaster risk science field, fundamental mitigation effect of mega-floating structures on the water level and hydrodynamic force caused by the offshore tsunami has been computationally investigated using SPH method taking into account the fluid-structure interaction (FSI).
