With the ever-increasing turbine inlet temperature and blade loadings, the thermal
management for the endwall of gas turbines is gaining wide attention. Specifically, the …

The design of an efficient cavity slot between assembled components, where purge air is
injected, is especially crucial to the durability and efficiency of an aero-engine, since the …

To investigate the effect of the upstream slot leakage on the endwall film cooling
characteristics, the PSP (Pressure Sensitive Paint) technology was applied to measure the …

The efficiency of the gas turbine engine has been enhanced by improving aerodynamic
performance and reducing heat load through control of secondary vortices according to the …

The secondary flow originated from the inherent pressure gradient inside the vane cascade
has a strong impact on the endwall cooling performance as the crossflow sweeps the …

Flow distortions from upstream combustors generate various and significant changes to the
patterns of endwall heat transfer for an aircraft engine. In this study, to model engine …

An upstream coolant injection that is different from the known leakage flow was introduced to
protect the turbine endwall. This coolant is ejected tangentially from a row of cylindrical …

Misalignment of gas turbine engines is caused by the difference in thermal expansion from
the design point when starting or stopping the engine, or when operating at partial load. This …

The aerothermal performance of a gas turbine could be improved by applying endwall
profiling to the nozzle guide vane. In this study, various thermal performance factors of flat …

Thermal barrier coating (TBC) is extensively employed to protect hot components in modern
gas turbines due to its high thermal resistance. Laser spraying is used to apply ceramic …
