| Abstract: | The various physical indexes of the flow passing through turbine and the abrasion conditions of turbines in the left bank of the Three Gorges Hydropower Station have been monitored. Based on these measured physical indexes and actual abrasion conditions, we analyze the abrasion mechanism of turbine. Through the analysis, we consider that through the field observation and numerical simulation, it can comparatively accurately predict the future abrasion of turbine, which can provide the basis for the transformation of check and repair system, |
