Abstract
High-speed particle image velocimetry measurements were performed at the exit of a pressurized lean-burn combustion chamber fueled with kerosene and operated at flight relevant conditions (elevated pressure and pre-heated supply air). The aim was to obtain information on the turbulent nature of the exhaust flow as this is of relevance for the modelling of aero-thermal dynamics of the combustor-turbine interface, such as heat transfer on the outlet guide vanes and turbulence induced noise. Two-component velocity data was sampled at 20 kHz along a narrow strip and used to obtain frequency spectra and correlations. Synchronously acquired chemiluminescence of the OH radical in the primary zone exhibited a notable tonal peak near 100 Hz that could also be detected in the circumferential velocity component at one operating condition.
