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

E3S 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.
