...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...

...Yi Wen; Xiaochu Zhang; Pu Wang The maximum operating efficiency of a centrifugal pump is different when it is parallel operated with different pumps. To study the reduction in the maximum operating efficiency of pumps in parallel operation compared with their rated efficiency, 28 pairs of pumps...

...Matthias K. Maess; Lothar Gaul Valve actuation and pump fluctuation in piping systems generate propagating sound waves in the fluid path which in turn can lead to undesired excitation of structural components. This vibro-acoustic problem is addressed by studying the propagation dynamics as well...

...Bin Liu; Mauricio Prado For any pumping artificial lift system in the petroleum industry, the free gas significantly affects the performance of the pump and the system above the pump. A model, though not a complete two-phase flow model, has been developed for the effective prediction of separation...

...Datong Sun; Mauricio Prado This study presents a new gas-liquid model to predict electrical submersible pumps head performance. The newly derived approach based on gas-liquid momentum equations along pump channels has improved the Sachdeva model (Sachdeva, R., Doty, D. R., and Schmidt, Z., 1988...

... and drill through the rocket. This approach was found to be effective due to minimizing the number of moving parts. High-pressure direct drive and intensifier pumps were developed for this application. It was found that intensifier-based pumps are more suitable for robust field use. The abrasive ammonia...

...B. Chatterjee; S. K. Gupta; H. S. Kushwaha; V. Venkat Raj In nuclear power plants, the primary heat transport system (PHTS) is designed according to ASME Section 3 Division 1. The PHTS together with Primary Coolant Pumps (PCPs) is designed so that the integrity under safe shutdown earthquake (SSE...
