Virial Approximation for Load and Loss in High-Speed Journal Bearings Using Pressurized Gases

Abstract: We consider steady, laminar, compressible lubrication flows in a high-speed two-dimensional journal bearing governed by the appropriate Reynolds equation. The thermodynamic states correspond to pressurized gases and are in the single-phase regime. Simple explicit formulas for the load capacity, power loss, and attitude angle are derived by applying the virial (or small density) expansions of pressure and shear viscosity to results developed in previous studies. The present virial approximation was compared to … Show more

“…the viscosity, bulk modulus and thermal expansivity (Chien & Cramer 2019 b ). The approximations for global parameters, including the total force and total friction loss, were also developed in Chien & Cramer (2019 a , b ). While the numerical and analytic results of Chien & Cramer (2019 a , b , c ) delineate the effects of pressurization for a simple two-dimensional configuration, the complication due to the three dimensionality of the flow has not yet been investigated in their analysis.…”
