Oil Film and Pressure Characteristics of the Friction Pair

OALib, 2018
In order to improve the friction performance of the valve plate and improve the oil film bearing capacity of the valve plate, the influence of the fluid-solid coupling on the performance of the oil film of the valve plate was studied. The lubrication characteristics of the surface texture of the valve plate was studied systematically based on the ...

Adverse-Pressure-Gradient effects on Turbulent Boundary Layers [PDF]

, 2018
Wall-bounded turbulence is present in many relevant fluid-flow problems such as the flow around wings, land and sea vehicles, or in turbines, compressors, etc. Simplified scenarios, such as the zero-pressure-gradient (ZPG) turbulent boundary layers (TBL)
