In future Ultra-High By-Pass Ratio turboengines, the turbomachinery noise (fan and turbine
stages mainly) is expected to increase significantly. A review of analytical models and …

Gas turbine engine efficiency and reliability is generally improved through better
understanding and improvements to the design of individual components. The life limiting …

A coupling method based on the overset grid approach has been successfully developed to
couple multi-copies of a massively-parallel unstructured compressible LES solver AVBP for …

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 …

Due to the repeated thermal cycling that occurs with the processing of each subsequent
layer, the microstructure of additively manufactured parts undergoes complex changes …

Swirling flows are now widely being used in modern gas turbine combustors to improve the
combustion characteristics, flame stability, and reduce emissions. Residual swirl at the …

This paper presents an investigation of the aerothermal performance of a modern
unshrouded high-pressure (HP) aero-engine turbine subject to nonuniform inlet temperature …

Gas turbines play an important role in power generation and propulsion. The simplification
of the real-engine condition during turbine design results in substandard gas turbine …

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 …

This paper describes a new engine-parts facility at the University of Oxford for high
technology-readiness-level research, new technology demonstration, and for engine …
