What is annulus area in a compressor?
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.
Thanks for the help
