Surface virtual texturing of the journal bearings of a three-cylinder ethanol engine

Purpose This paper aims to numerically investigate the surface texturing effects on the main bearings of a three-cylinder ethanol engine in terms of the power loss and friction coefficient for dynamic load conditions. Design/methodology/approach The mathematical formulation considers the Partir-Cheng modified Reynolds equation. The mass-conserving Elrod-Adams p -θ model with the JFO approach is used to deal with cavitation. A fluid-structure...
