1. A method of mixing fluid flows, the method comprising:
conveying a first fluid flow along a first flow passage of a primary tube from an inlet end of the tube toward an outlet end of the primary tube, the outlet end of the primary tube being open to an end wall defining an exit orifice, the exit orifice defining a central axis and a primary flow direction of the first fluid flow along the first flow passage being substantially parallel with the central axis;
while conveying the first fluid flow along the first flow passage, conveying a second fluid flow along a second flow passage;
altering a flow direction of the second fluid flow from the second flow passage to a plurality of nozzle openings in an injection cap mounted to the outlet end of the primary tube such that the second fluid flow mixes with the first fluid flow within the first flow passage to generate a mixed fluid flow; and
dispensing the mixed fluid flow through the exit orifice.
