A Thermohydrodynamic Analysis of a Misaligned Mechanical Face Seal

Abstract

A thermohydrodynamic analysis is performed for a misaligned mechanical face seal. Temperature variations both across the sealing gap and along its radial and circumferential extent are considered. The energy equation is solved analytically and temperature distribution is presented in an implicit form. It is shown that, in most practical cases, the amplitude of temperature variation along the seal circumference due to misalignment is negligible compared to the mean temperature. The radial temperature distribution can be obtained by solving an equivalent aligned seal whose face separation is reduced by a factor that contains the effect of misalignment.
