3-D Viscous Flow Analysis of a Mixed Flow Pump Impeller
International Journal of Rotating Machinery, 2001 This paper presents the results of a study using a coarse grid to analyze the flow in the impeller of a mixed flow pump. A commercial computational fluid dynamics code (FLOTRAN) is used to solve the 3-D Reynolds Averaged Navier Stokes equations in a ...

Experimental Study on Cavitation in Mixed-Flow Pump Impellers
Transactions of the Japan Society of Mechanical Engineers, 1963 Several mixed-flow pump impellers were tested in a test pump for the purpose of studying the effects of the number of vanes and the inlet edge shape on their performance and cavitation characteristics. The shockless entry flow rates were obtained from the incipient cavitation conditions and inlet flow deviation angles were found, their degree varying ...

Modelling of vertical shaft of mixed-flow pump [PDF]
Archive of Mechanical Engineering, 2013 Abstract The aim of the work was modelling of shaft and calculation of natural vibration frequencies and critical rotations of a large-size, vertical mixed flow pump of total length l=4866 mm. Equations of motion were determined analytically, and then calculation results were verified by numerical modelling. The difficulty of the problem consisted

Performance Evaluation and Dimensional Analysis of Multistage Helicoaxial Pump for Two-Phase Flow
International Journal of Turbomachinery, Propulsion and Power, 2019 A four stage helicoaxial pump was tested under varying operating conditions. A range of inlet pressures, rotational speeds (3000, 3600 rpm), and gas void fractures (GVFs) were considered for two fluid viscosities.

Hydrodynamic performance enhancement of a mixed-flow pump
IOP Conference Series: Earth and Environmental Science, 2012 This paper presents an optimization procedure based on a radial basis neural network surrogate model for design of a vaned diffuser in a mixed-flow pump. Numerical analysis of fluid flow in a mixed-flow pump has been carried out by solving three-dimensional Reynolds-averaged Navier-Stokes equations with the shear stress transport turbulence model.
