Thermoelastohydrodynamic Behavior of Hydrostatic Thrust Bearings

open access: yesHydraulics & Pneumatics, 1990
The thermoelastic behavior of hydrostatic thrust bearings is analyzed numerically. Mineral oils, HWCF, seawater, and tap water are studied as working fluids. The physical properties of these fluids are expressed as a function of temperature and pressure. The heat transfer and thermoelastic distortion of the bearings are considered.
