Abstract:
Embodiments of the present invention include a method and system for carrying out vapor-phase lubrication of a component, such as a bearing for example. The method and apparatus can be applied to a turbine engine. The method includes the step of directing a first stream of fluid containing atomized lubricant to the component at a first velocity. The system provides a first fluid injection system configured to perform the first step. The method also includes the step of directing a second stream of fluid at a second velocity less than the first velocity to the component. The second stream is for controlling a temperature of the component. The system provides a second fluid injection system configured to perform the second step. Both of the directing steps are carried out concurrently.
