Thermo-hydrodynamic lubrication in hydrodynamic bearings
Thermo-hydrodynamic lubrication in hydrodynamic bearings constitutes the third part of a series dedicated to hydrodynamic bearings.Internal Combustion Engine Bearings Lubrication in Hydrodynamic Bearings describes in detail the physical properties of lubricants that play an essential role in the hydrodynamic process, followed by the equations of hydrodynamic lubrication and the models for numerical solving. The description of “elastohydrodynamic” (EHD) models also forms part of the content of the first volume.
Volume 2 Mixed Lubrication in Hydrodynamic Bearings is dedicated to the study of mixed lubrication. The role played by the roughness of surfaces – in terms of hydrodynamics on the one hand, and in terms of contact of the surface asperities on the other hand – is analyzed in detail and completed by a presentation of the corresponding numerical techniques. This volume also deals with the problem of surface wear in this context.

he thermo‐hydrodynamic (THD) method in terms of lubrication consists of not only determining the temperature fields in the fluid, but also in the surrounding solids in connection with the hydrodynamic pressure field in the lubricating film. For this, two supplementary equations are associated with the Reynolds equation whose main parameter is pressure: the energy equation that enables the determination of the temperature at every point of the fluid and the Fourier equation that allows the determination of the temperature in the solids.
The global thermal balance method applied to a bearing consists of determining an average functioning temperature of the hydrodynamic bearing, which is not only the temperature of the lubricating film itself, but also of the surrounding solids.
