In this study, experimental and analytical investigations are carried out in order to determine the steady state performance curves of a centrifugal pump. The pump rotor of the hydraulic facility (TE-83), available at the fluid laboratory of the National Engineering School of Sfax (ENIS), is used for the steady state calculations. The characteristic curves (flow-head) of the pump were determined by measuring the difference between the outlet and the inlet pressures for different steady flow rates. The curves were plotted for various values of the rotating speed. For each speed the head is recorded then plotted at different discharge openings. Results are further processed to determine the head and flow coefficients. These coefficients are obtained by applying the theory of dimensional analysis and similitude. The head coefficient is plotted versus the flow coefficient to form a curve of these two dimensionless numbers using only one machine. This curve can then be used to give information for any machines geometrically similar to the test machine. © Springer International Publishing Switzerland 2015.

This paper shows numerical simulations of the three-dimensional fluid flow through centrifugal pump. The standard turbulence model k - ɛ is adopted to describe the turbulent flow process. These simulations have been made with a steady calculation using the multiple reference frames (MRF) technique to take into account the impeller volute interaction. The computational domain composed by a single stator and rotor blade passages is discretized by a structured multiblock meshes. The transport equations associated with the appropriate boundaries conditions are solved by the ANSYS CFX finite-volume code. In addition, the steady state simulation are made to construct the performance for centrifugal impeller. This work is aimed to analyze the pressure and velocity distribution inside the pump impeller using the ANSYS-CFX computational fluid dynamics simulation tool. © Springer International Publishing Switzerland 2015.
