Abstract
A gas-buffered brush seal assembly and associated method are provided. The seal assembly includes at least one brush seal that defines an interface with a rotatable member. The seal assembly is configured to deliver a gas to the interface so that the gas at least partially prevents the flow of a fluid therethrough. In addition, the seal assembly can be adjustable so that the flow of the fluid is controlled by adjusting the flow rate of the gas through the seal assembly.
