...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...

...Frantisek L. Eisinger; Robert E. Sullivan Fatigue cracks from high cycle vibratory loading have developed in a centrifugal fan impeller after a relatively short period of operation. Based on vibration tests of the impeller and acoustic analysis of the internal spaces of the fan, structural-acoustic...

... equations. The model can predict pressure and void fraction distributions along impellers and diffusers in addition to the pump head performance curve under different fluid properties, pump intake conditions, and rotational speeds. The new two-phase model is based on the same assumptions used by Sachdeva...
