The high pressure (HP) turbine is subject to inlet flow nonuniformities resulting from the
combustor. A lean-burn combustor tends to combine temperature variations with strong swirl …

Recently developed lean-burn combustors offer reduced NO x emissions for gas turbines.
The flow at exit of lean-burn combustors is dominated by hot streaks and residual swirl …

Unsteady component interaction represents a crucial topic in turbomachinery design and
analysis. Combustor/turbine interaction is one of the most widely studied topics both using …

In turbomachinery, the prediction of component life is crucial. It has been found that the
variability of gaps, fillets and small geometries, due to manufacturing process and in service …

With the progress of aviation technology, turbine aerodynamic, as one of the major support
subjects for the development of aero-gas turbine, has experienced a rapid development in …

This paper presents experimental measurements and computational predictions of surface
and end wall heat transfer for a high-pressure (HP) nozzle guide vane operating as part of a …

Conjugate heat transfer (CHT) analyses were conducted on the film-cooled first stage vane
of GE-E 3 engine to reveal the influences of inlet swirl and hot streak (HS) on vane film …

Nowadays, the lack of confidence in the prediction of combustor-turbine interactions and
more specifically our ability to predict the migration of hot spots through this interface leads …

Understanding the interaction between the combustor and turbine subsystems of a gas
turbine engine is believed to be key in developing focused strategies for improving turbine …

A high-pressure vane (HPV) equipped with a realistic film-cooling configuration has been
studied. The vane is characterized by the presence of multiple rows of fan-shaped holes …
