Figure 7 shows the outer member of split vane impeller for the second stages for 0 and 20%GVF testing.In the case of 0 GVF testing，erosion rate was minimal and blade retained overall length.The outer member experienced significant erosion for 20%GVF testing.More than half of the blade of the first stage impeller was eroded；the leading edge was also significantly eroded.This may have been caused due to impingement of the sand particle with higher force due to various factors.Phase separation causing higher shear，higher turbulence due to the special design of the blades，and reduced lubricity due to gas accumulation may be the major factors.The presence of gas had a profound effect on the wear mechanism.Wear across subsequent stages was lower due to decreased GVF.Figure 8 shows that the hub sidewall for the water only test experienced significantly less wear than the 20%GVF.The shroud sidewalls experienced similar wear.
