| Abstract: |
The prime
objective of this paper is to present the details of the experimental
investigation and measurements made in an axisymmetric 5° conical diffuser model. The flow through a
diffuser is studied with and without the inlet flow distortion. A simple
cylindrical bluff body placed at the inlet of the diffuser creates the inlet
flow distortion. A 5 mm
diameter five-hole pitot sphere of cobra type has been used along with
electronic digital manometers for the measurements. The velocity at the near
wall regions and wake regions are well captured with the five-hole probe. The
measurements along the entire length of the model at different stations, allow
the determination of axial mean velocity component and pressure field
parameters, which provide comprehensive information to aid and understand such
complex flows. Performance and flow characteristics along the centerline of
diffuser are presented.
