ABSTRACTThis study aims at improving the performance of a centrifugal pump by using different angular diffusers on the downstream side of the centrifugal pump impeller. Numerical and experimental studies have been carried out on different vaned and non-vaned diffuser with three different wall divergence angle (α) of 0°, 5° and 10° to achieve that purpose. The data analyses show good agreement between the numerical and experimental results. They reveal profound effect of the divergence angle (α) of angular vaned diffuser on the head and overall efficiency of centrifugal pumps especially at high

Abstract:
Abstract In the previous study of a centrifugal pump with a vaned diffuser, it was confirmed that the flowrate at the onset of rotating stall was shifted to the lower flowrate by slitting the diffuser vanes. As the CFD result, it was found that the jet flow from pressure-side to suction-side impinges backflow near the suction surface and it suppresses to expand toward the diffuser inlet. However, it is difficult to say that the optimized shape and slitting position have been sufficiently studied. Therefore, in this study, we investigated the effect of slitting on the pump performance and inter

A centrifugal compressor is a mechanical device that helps to achieve higher pressure ratios at lower mass flow rates. It is used in many applications such as turbochargers, cruise missiles, and turbojet engines where compact high pressure ratio compressors are required. The performance of a centrifugal compressor is greatly influenced by instabilities like stall and surge, which decrease the operating range and the efficiency of a compressor.

Abstract:
Abstract The use of fully unsteady CFD computations for centrifugal turbomachinery during preliminary design calculations is still infeasible due to the extensive computational efforts required. Most design-based CFD analyses for centrifugal machines are conducted on individual components using steady-state calculations. These steady calculations do not represent the interactions of the components with their neighboring blade rows, including the upstream rotating component. In this paper, commonly accepted CFD procedures for steady-state calculations are applied to the components of a centrifu
