End-wall slotting effects on axial velocity density ratio of supersonic compressor cascade
Kongqi donglixue xuebaoIn addressing the issue of adjusting the axial velocity density ratio in experiments with supersonic compressor planar cascades, numerical simulations were employed to investigate the impact of end-wall slotting on the flow field of the supersonic ...

Turbulence Amplification with Incidence at the Leading Edge of a Compressor Cascade [PDF]
International Journal of Rotating Machinery, 1996 Detailed measurements, with a two‐component laser‐Doppler velocimeter and a thermal anemometer were made near the suction surface leading edge of controlled‐diffusion airfoils in cascade. The Reynolds number was near 700,000, Mach number equal to 0.25, and freestream turbulence was at 1.5% ahead of the cascade.It was found that there was a localized ...

Advanced Engineering Materials, EarlyView.Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Effect of Leading-Edge Tubercles on Compressor Cascade Performance [PDF]
AIAA Journal, 2016 Tubercles are modifications to the leading edge of an airfoil in the form of blunt wave-like serrations. Several studies on the effect of tubercles on isolated airfoils have shown a beneficial effect in the post-stall regime, as reduced drag and increased lift, leading to a delay of stall.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
