Abstract:
The standard k–e turbulence model and the wall function are adopted to
solve 3D turbulent flow field in the impeller of a centrifugal pump. The
influences of the blade profile on speed distributions, press
distributions and pump performance are analyzed. The flow regulation
pattern in the impeller of a centrifugal pump is also investigated. A
redesign and optimizing method of the impeller blade profile based on
numerical analysis of 3D turbulent flow is put forward. The results show
that the proposed method is a very outstanding tool to carry out the
redesign and optimizing of the impeller blade profile.
