Pelton Turbine bucket and check its suitability for the the pelton turbine. The literature on Pelton turbine design available is scarce; this work exposes the theoretical and experimental aspects in the design and analysis of a Pelton wheel bucket, and hence the designing of Pelton wheel bucket using the standard rules.
Turbine applications, especially those in high-temperature segments, are some of the most difficult-to-manufacture components due to complex workpiece geomet...
If cracks are discovered when very small, there is the possibility that they can be ground out with a consequent reduction in aerodynamic efficiency of the turbine stage and with an imbalance which must be cured possibly by correspondingly grinding an opposed bucket. Since turbine buckets are produced from high-cost superalloys, the cost of ...
