Lubrication Characteristics of a Temperature-Viscosity-Controlled Hydrodynamic Journal Bearing: Prototype and Experiment

This study experimentally investigated the possibility of controlling the static lubrication characteristics of hydrodynamic journal bearings by cooling and heating locally. A test rig of a plain journal bearing was built to observe the pressure and temperature distributions, bearing eccentricity, a...
