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. The numerical method was based on a weakly
coupling for flow-wall interaction and one-way coupling for gas-solid twophase flow [1]. The computational target was a high-pressure turbine vane
designed by JAXA [2]. The turbine material was CMC with EBC. The results
showed that the small particles damage the stator vanes, but the large particles
significantly erode the rotor blades, and the deterioration of the
aerodynamic performance is the most severe due to small particles.},
