研究概要

マルチフィジックス計算科学シミュレーション技術の開拓

    In order to solve the energy and environmental problems, to realize the safe and secure society, and to create new industry and market in the world, the development of the super-precise and super-miniaturized system and the high-functional and high-performance materials is strongly required in a wide variety of research fields such as fuel cell, solar cell, clean energy, micromachine, tribology, electric car, aerospace instrument, power plant, hydrogen station, electronics, etc.
    Especially, the recent system, process, and material technologies constitute of multi-physics phenomena including chemical reaction, friction, impact, stress, fluid, photon, electron, heat, electric and magnetic fields etc. and then the deep understanding of the above multi-physics phenomena are significantly essential. However, the traditional simulation methods in the mechanical engineering fields such as fluid mechanics, finite element, finite volume, and other methods cannot clarify the multi-physics phenomena including the chemical reactions on electronic- and atomic-scale.
    Therefore, Kubo laboratory is developing new multi-physics computational simulation technology based on first-principles molecular dynamics method for pioneering next-generation system, process, and material design and development in the mechanical engineering fields.
    Furthermore, Kubo laboratory applies the above originally developed simulation methodology to a lot of energy problems, environmental problems, and nano-technology in a wide variety of research fields such as fuel cell, solar cell, clean energy, micromachine, tribology, electric car, aerospace instrument, power plant, hydrogen station, electronics, etc. and aims to realize the high-level and high-accuracy system, process, and material design related to the mechanical engineering.

マルチスケール計算科学シミュレーション技術の開拓

    In order to develop the super-precise and super-miniaturized system and the high-functional and high-performance materials for next-generation, the establishment of multi-scale simulation technology is significantly essential. For example, recently much attention has been paid to the fuel cell as next-generation energy system. Fuel cell is an integrated technology of mechanical engineering, continuum mechanics, electrochemistry, surface science, catalysis, chemical engineering, etc. and is a notable example of which property and functionality on nano-scale influences macro-scale performance and degradation property. Then, the deep understanding of the multi-physics phenomena from electronic-scale to macro-scale is essential in the fuel cell system. As another example, the development of new tribology system is highly required for contributing to energy and environmental problems. In the recent tribology system, the chemical reactions on atomic-scale significantly affect its friction and lubrication property on macro-scale. Moreover, in the next-generation micromachine and MEMS system, the realization of super-precision and super-miniaturization is strongly required and then the detailed clarification of the multi-physics phenomena from nano-scale fabrication to macro-scale mechanical property is essential.
    Therefore, Kubo laboratory is pioneering and developing the multi-scale simulation technology by integrating a wide variety of simulation methods from the first-principles molecular dynamics on electronic-scale to the continuum mechanics on macro-scale. Then, Kubo Laboratory aims to realize the high-level and high-accuracy system, process, and material design from electronic-scale to macro-scale which can not be achieved by the conventional simulation methods. Our simulation outcomes are strongly contributing to solving energy and environmental problems, realizing safe and secure society, and creating new industry and market.
