Synergetic effects of surface texturing and solid lubricants to tailor friction and wear – A review (2021, background): “increased lubricant supply [53-56] and increased inlet suction [53, 57].”
Micro-Textures in Concentrated Conformal-Contact Lubrication: Effects of Texture Bottom Shape and Surface Relative Motion (2008, methodology): “Most recently, Olver et al. [28] and Fowell et al. [ 29 ] identified the load support mechanism of inlet suction.”
Efficiency of laser surface texturing in the reduction of friction under mixed lubrication (2014, methodology): “Such pressure build-up can be estimated either by solving the Reynolds [11] or the Navier-Stokes equation [13].”
Combined friction and wear reduction in a reciprocating contact through laser surface texturing (2016, background): “In 2006, the concept of “inlet suction” was identified in Olver and Fowell’s work [29,30], whereby the reduction in pressure afforded by cavitation as lubricant expands into a pocket at the contact inlet leads to an increase in lubricant entrainment and hence film thickness.”
Hydrodynamic lubrication of textured surfaces: A review of modeling techniques and key findings (2016, background): “Additionally, lift can only be generated when the cavitation pressure is inferior to the supply pressure, as this will provide the necessary pressure gradient to ensure a sufficient lubricant supply (inlet suction [60] [61], see Fig.”
Multi-Scale Surface Texturing in Tribology—Current Knowledge and Future Perspectives (2019, background): “Furthermore, the subambient pressure zones formed in textures close to the contact inlet due to the fluid cavitation phenomenon responsible for the aforementioned micro-hydrodynamic bearing effect may also contribute to drawing additional lubricant into the contact (inlet-suction effect) [27,29,30].”
