Experimental verification of a CFD model intended for the determination of restitution coefficients used in erosion modelling

open access: yesE3S Web of Conferences, 2017
Erosion caused by solid particles transported with the steam or flue gas has a negative impact on the power unit reliability and availability. The erosion rate depends inter alia on the restitution of the particle velocity upon impact.
