...Amro M. Al-Qutub; Atia E. Khalifa; Faleh A. Al-Sulaiman The effect of V-cut at impeller blades’ exit on internal pressure fluctuations, case vibration, and performance of a double volute boiler-feed pump has been investigated. Scaled model pump and two impellers, with and without the V-cut, were...

...Behrooz Farshi; Jalal Bidabadi Gas turbine disks are subject to mechanical stresses due to centrifugal forces exerted by the blades, as well as thermal stresses due to high temperature gradient. High stresses in the presence of elevated temperatures cause the rotating disk material to undergo...

.... Remnant creep life at the center of the rotor is based on the time while accumulated creep strain reaches its threshold level. Creep rupture could occur at other locations such as the outside surface of the shaft at disks∕shaft radii or blade fixings. Finite element analyses were carried out to analyze...

...Fred V. Ellis A metallurgical failure analysis was performed for the stage 17 gas turbine rotating blade and stationary vane. Four pieces, including the failed rotating and stationary blades, were removed from the air-compressor section of a gas turbine. The damaged components were found during...
