Claim 12:
13. A method of atomizing a fluid, the method comprising:
coupling an inner member to one or more outer members positioned radially outward of the inner member, the inner member having an axis and defining an interior first-fluid flowpath from a supply end of a fluid atomizer to a discharge end of the fluid atomizer, the inner member and outer members defining a second-fluid flowpath extending from a second-fluid supply conduit proximate the supply end of the fluid atomizer to a second-fluid discharge plenum proximate the discharge end of the fluid atomizer, the second-fluid flowpath comprising a tangential conduit spiraling along said axis as the tangential conduit extends from an entry plenum in fluid communication with the second-fluid supply conduit to a terminal end of an exit plenum space axially downstream of the entry plenum, an annulus downstream from and in fluid communication with the tangential conduit, and the second-fluid discharge plenum downstream from and in fluid communication with said annulus, wherein
the annulus extends axially between the inner member and the one or more outer members from the exit plenum to the second-fluid discharge plenum,
the fluid flows from the entry plenum through the tangential conduit,
the tangential conduit terminates at the exit plenum, the entry plenum disposed between (1) a downstream end of a first outer member of the one or more outer members and (2) the inner member, and
the downstream end of the first outer member is coupled to an upstream end of the second outer member; and

directing the fluid from the second-fluid supply conduit through the second-fluid flowpath.
