Numerical and experimental study of a small-scale sliding vane pump

Abstract EN

Automotive pumps have two forms either hydraulic or centrifugal one.

Hydraulic pumps are
usually positive displacement pumps.

In the automotive industry, vane pumps have wide range
of applications including fuel pumping, power steering system and automatic transmission
system.

Fluid behavior costs a lot to be seen inside the pump during operation experimentally
however, predictive tools based on Computational Fluid Dynamics (CFD), has become a valid
alternative approach to pump design and optimization.

In this paper, CFD analysis for oil vane
pump will be shown including different (number of vanes) models and different gap heights.

The numerical model was built up with ANSYS (Fluent) using dynamic mesh code and it was
validated by comparing the obtained numerical results with the experimental data of (four
vanes) pump.

The model gave a good agreement with the experiment results, with maximum
deviation mm gave the largest flow-rate and best performance as well.
