Abstract

A fluid distributor comprises a first conduit extending along a first elongated axis and a second conduit circumscribing the first conduit. A first area comprises a cross-sectional flow area of the first conduit taken perpendicular to the first elongated axis. The first conduit comprises a first plurality of orifices comprising a first combined cross-sectional area. The second conduit comprises a second plurality of orifices comprising a second combined cross-sectional area. A first ratio of the first area to the first combined cross-sectional area can be about 2 or more. A second ratio of the first combined cross-sectional area to the second combined cross-sectional area can be about 2 or more. An angle between a direction of an orifice axis of a first orifice of the first plurality of orifices and a direction of an orifice axis of a first orifice of the second plurality of orifices can be from about 45° to 180°.
