Design study of a novel regenerative pump using experimental and numerical techniques [PDF]
, 2010 This paper presents a numerical and experimental analysis of a new regenerative pump design. The complex flow-field within regenerative pumps represents a significant challenge to previous published mathematical models. The new pump design incorporates a

Model predictions and experimental results for the rotordynamic characteristics of leakage flows in centrifugal pumps [PDF]
, 1993 The role played by fluid forces in determining the rotordynamic stability and characteristics of a centrifugal pump is gaining increasing attention. The present research investigates the contributions to the rotordynamic forces from the discharge-to ...

Pumping crude oil by centrifugal impeller having different blade angles and surface roughness
Journal of Petroleum Exploration and Production Technology, 2016 Centrifugal pumps are extensively used in the oil and gas industries and the pump performance drops with higher viscosity and higher surface roughness of the pump impeller, and the impeller design parameters have significant effect on the pump ...

The influence of impeller eccentricity on centrifugal pump
, 2017 In order to study the influence of the impeller eccentricity on the performance of centrifugal pump, the k–ε turbulence model was selected, and ANSYS CFX was provided for numerical simulation calculation of the centrifugal pump with impeller offsets of 0,
