Jan 3, 2025 · This study delves into the influence of key parameters like airfoil blade thickness, outlet angle, and curvature on the internal flow dynamics and vibration characteristics of these pumps.

Sep 1, 2016 · This paper deals with a comparative study of the outlet pressure-energy between a conventional and normal blade impeller and an airfoil-shaped blade impeller of a centrifugal pump.

In an airfoil, the mean line curvature is designed to change the flow direction, the vane thickness is for strength and the streamlined shape is to delay the onset of boundary layer separation.

Nov 18, 2017 · Given that an axial flow pump impeller is likely to be relatively small in diameter (lets say a couple meters at the most even in a large unit) then it would be unlikely that a single airfoil would be appropriate due to the change in chord, pitch and linear velocity over the length of …

The results presented in this paper make it possible to design axial flow pumps by using singularity approach, and will help pump design engineers use the new way in their design practice.

Feb 16, 2024 · In summary, an airfoil can be described using six parameters: the x and y coordinates (xd, yd) of the control point P 2, the blade stagger angle (γ), the blade solidity (σ), the circulation correction factor (⁠ λ η ⁠), and the thickness coefficient (Tr).

Abstract: This paper deals with a comparative study of the outlet pressure-energy between a conventional and normal blade impeller and an airfoil-shaped blade impeller of a centrifugal...

Feb 25, 2022 · To obtain the influence of airfoil camber on the internal pressure fluctuation of a bidirectional axial-flow pump, the unsteady Reynolds time-averaged Navier–Stokes (URANS) equation was solved to predict the internal flow structure under three airfoil camber cases.

The invention discloses a centrifugal pump high-efficiency low-noise airfoil blade design method based on pump internal flow and pressure pulsation, which is characterized in that CFD...

Aug 22, 2018 · A new bi-directional airfoil, obtained by lowering the bent airfoil camber and thickening the bone line bi-directionally, is proposed. Two bi-directional axial flow pumps, with the SA blades and the arc airfoil (AA) blades, respectively, were designed to …
