Fluid–solid coupling simulation in an aero-engine annular combustor with full film cooling is
conducted to investigate the integrated contribution of combustion and cooling to the thermal …

Secondary flows in the cooling jets are the main reason for the degradation of the cooling
performance of a film-cooled blade. The formation of kidney vortices can significantly be …

Heat transfer continues to be a major field of interest to engineering and scientific
researchers, as well as designers, developers, and manufacturers. Considerable effort has …

Advances in cooling technologies have enabled turbine designers to push the turbine entry
temperature to temperatures as high as 1700° C which are well beyond the material limit of …

In this paper, effects of four different hole configurations on film cooling performance and
particle deposition are investigated numerically on a curved surface. The RNG k-ε …

Serpentine nozzles more easily deform and damage due to high-temperature airflow
because of their multi-bend channel configuration. Therefore, film cooling technologies …

In the suction surface gill region of the turbine blade, three representative regions with a
favorable pressure gradient (FPG), adverse pressure gradient (APG), and pressure gradient …

As the load of a modern turbine is increasing, the turning angle and the flow acceleration is
increasing. The effects of streamwise pressure gradient (SPG) and wall curvature on film …

The serpentine nozzle is widely used in military unmanned aerial vehicles to improve their
viability. The film cooling technology should be used in the serpentine nozzle to cope with …
