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.
