Three-Dimensional Numerical Flow Simulation in a Centrifugal Pump

This paper shows numerical simulations of the three-dimensional fluid flow through centrifugal pump. The standard turbulence model k - epsilon 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.
