Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Effects of Surface Roughness on Film Cooling [PDF]
Volume 4: Heat Transfer; Electric Power; Industrial and Cogeneration, 1996 A flat plate test section was used to study how surface roughness representative of an in-service turbine affects the film cooling adiabatic effectiveness and heat transfer coefficient for a round hole geometry. The injection was from a single row of round film cooling holes with injection angle of 30°.

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Shape optimization of a bended film-cooling hole to enhance cooling effectiveness
Journal of Thermal Science and Technology, 2019 To improve cooling effectiveness of film-cooling hole, bending of hole was investigated and optimized using surrogate modelling based on three-dimensional Reynolds-averaged Navier-Stokes analysis. The turbulence was modeled using a shear stress transport
