An inert gas distribution system nozzle has a fluid flow path from an inlet 10 into a chamber 32, through at least one passage 34, to an outlet 40 for expelling the fluid from the nozzle. The chamber has a larger cross-sectional area than the passage normal to the flow path, which may allow the fluid to expand into a mist in the chamber and condense in the passage. The nozzle may be used in an aircraft, in fluid communication with a fuel reservoir of the aircraft. Preferably, the cross-sectional area of the passage is less than 10% that of the chamber, and the passage length is at least 80% that of the chamber. The passage may promote laminar flow of the fluid. The nozzle may have a first part 210 with a cavity 212 and a second part 220 with a protrusion 222 inserted into the cavity so that the chamber is defined between the end of the protrusion and the first part, and the passage is defined between the side of the protrusion and the first part.
