Abstract

A thermohydrodynamic model is presented to analyse the lubrication film between seal faces with provision for surface roughness. A simplified energy equation is derived and solved analytically. The variation of temperature in both radial and axial directions is considered. The effect of various parameters on the thermal behaviour of sealing gap is explored. It is shown that the temperature variation across the sealing gap can be significant, raising questions about the validity of constant viscosity solution often made in analyses.
