Turbine blade and steam piping may have been damaged due to droplet erosion. The objective of this study is to propose the simulation model based on the damage phenomenon for predicting the erosion behavior. We developed a simulation model of droplet erosion of turbine blade material, that is martensite stainless steel containing 15% Cr.
