    It's not a general term as far as I know, but it can be the area between cylinder and the piston.

    Sorry for being not clear. I was talking about the annulus area of a compressor in a gas turbine engine, not a reciprocating one.

    It's the flow area in the compressor. It's an annulus because it is formed by two concentric circles i.e. the rotor and the compressor case.
