Abstract

Kinetic energy and loss coefficients are presented over a realistic range of swirl angle for an axial annular-conical diffuser with and without tip leakage flow. The analysis of a measured flow field shows that swirl induces the rotation of a recirculation zone downstream of the hub causing additional losses. This study is based on results of experimental investigations conducted in a test rig which is a 1:10 scale model of a typical gas turbine exhaust diffuser. A control volume analysis which applies conservation equations between inlet and outlet of the diffuser is used to evaluate its losses. The flow parameters at the cross sections are averaged values derived by applying the conservation of mean integral characteristics of the real flow, assuming the flow is steady, incompressible, and axisymmetric.
