The Parameters for THD Lubrication Flow
AbstractParameters of thermohydrodynamic (THD) lubrication are discussed for the laminar and turbulent regimes. The scales of pressure of temperature are analytically obtained, and are used to measure the variations of density and viscosity. Dominant THD parameters are identified by inspecting the practical applications.
