Investigation on the Time-Variant Flow in a Single-Blade Centrifugal Pump
Effects of the time-variant flow in a single-blade pump are investigated by numerical and experimental methods. For a numerical approach the three-dimensional, viscous, unsteady flow field in the pump has been achieved by solving the unsteady Navier-Stokes equations (URANS) with a commercial solver. From the obtained periodic flow field the time-variant forces acting at the wetted impeller surf...
متن کاملInfluence of Vaned Diffuser on Dangerous Blade Vibration Due to Blade Flow Interactions in a Centrifugal Compressor
Influence of diffuser vane position on dangerous blade vibration due to blade flow interactions at part load operating condition was investigated in a centrifugal compressor. By means of some measurement and analysis techniques a mechanism of interaction between blade vibration and circumferential flow condition in the impeller with vaned diffuser was determined, which is a cause of dangerous b...
متن کاملNote: Radial-thrust combo metal mesh foil bearing for microturbomachinery.
This Note proposes a novel radial-thrust combo metal mesh foil bearing (MMFB). Although MMFBs have advantages such as higher stiffness and damping over conventional air foil bearings, studies related to MMFBs have been limited to radial MMFBs. The novel combo MMFB is composed of a radial top foil, thrust top foils, and a ring-shaped metal mesh damper--fabricated by compressing a copper wire mes...
متن کاملPart Load Flow in Radial Centrifugal Pumps THÈSE
Centrifugal pumps are required to sustain a stable operation of the system they support under all operating conditions. Minor modifications of the surfaces defining the pump’s water passage can influence the tendency to unstable system operation significantly. The action of such modifications on the flow are yet not fully understood, leading to costly trial and error approaches in the solution ...
متن کاملEffect of Impeller Blade Exit Angle on the Performance of Centrifugal Pump
-Changing some geometric characteristic of the impeller in centrifugal pumps improves their performance. It is known that blade exit angle plays very important role in the performance of a centrifugal pump. To investigate effect of blade exit angle on the performance of centrifugal pump by means of experiment is very expensive and lengthy process. Due to expensive and lengthy process, it can be...
