Gas bearing and seal design is based on the theory of gas lubrication. Isothermal gas lubrication theory has been applied to gas bearings and seals since the 1970s. However, the increasing operational speed, pressure and temperature of modern machinery has caused thermal hydrodynamic lubrication problems, accompanied by surface distortion. Load capability can be reduced as a result of these problems, leading to the failure of gas bearings and seals. In view of these developments, Thermo-hydrodynamic Lubrication and Seals provides contemporary theory and method for thermo-hydrodynamic lubrication analysis for the design of gas bearings and seals. The book describes gas-thermo hydrodynamic lubrication theory and design methods of a gas face seal. The title includes information on gas state equations and gas property, derivation of gas thermo-hydrodynamic lubrication equations, the theory of isothermal gas lubrication, thermal gas lubrication of rigid surfaces, gas thermoelastic hydrodynamic lubrication of face seals, vapor-condensed gas lubrication of face seals, experimental methods, and the design of gas face seals. The title provides state-of-the-art practical knowledge based on fifty years of research and application.
