Abstract Recently, ceramic matrix composites (CMCs) are expected to utilize for the components of gas turbine engines due to its low density, high strength, and high rigidity in the high-temperature condition. The environmental barrier coating (EBC) is a key technology for the practical application of CMC to prevent surface regression from particulate and water vapor environments. However, the anti-erosion characteristics of CMC and EBC have not been clarified. In the present study, the authors performed numerical simulations of particulate erosion phenomena in a high-pressure turbine first stage to investigate the differences in the damage pattern and the performance between particle sizes.… More >

Abstract The establishment of the process and material design technology based on theoretical science at electronic- and atomic-level is one of the important subjects in order to solve the energy and environmental problems, to realize the safe and secure society, and to create new industry and markets. Especially, the recent material, process, and system 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 essential. Previously, continuum simulations such as finite element method have been employed for the investigation on… More >
