Abstract: This work presents the results of a detailed study of the effect of particle characteristics on the particle dynamics and on the resulting pattern of blade impacts in a two stage axial flow gas turbine operating with particle laden flows. The particle dynamics computations combine the particle-blade impact characteristics, as determined from a three dimensional trajectory analysis with the particle rebound characteristics, which are obtained from experimental data. The results show the pattern of blade impacts in all stationary and rotating blade rows for fly ash and for sand particles. The results demonstrate that drastically different patterns of particle blade impacts are associated with the different particles.
