Abstract

The flow conditions within the fluid passages of a closed face impeller is difficult to visualise without the application of numerical analysis to simulate these flows in a computer based model. Particle Image Velocimetry (PIV) and Laser Doppler Velocimetry (LDV) can give us some insight into the flows at the inlet and the outlet of the impeller, but this is of limited use as it doesn’t show what is happening behind the shroud. The impeller that is being analysed has been provided by Tyco Flow Control/Pumping Systems, and is from their 125x100-500 ISO Pump running at 4 Pole speed (1482 RPM). The impeller has been modelled in 2d using the original AutoCAD drawings and Pro/Engineer to produce a file that can be read in Gambit. After meshing in Gambit, the model was solved using the commercial package Fluent to solve the 2D Reynolds Averaged Navier Stokes equations in a rotating polar co-ordinate system. The flow conditions present in the impeller confirmed some of the suspicions about the orignal design, but some unexpected flow conditions were found, which provides insight into some phenomena seen in service.
