Abstract:
A fluid mixing apparatus comprising:a first conduit adapted to carry a primary fluid flow through said fluid mixing apparatus, wherein said first fluid conduit includes a first end and a second end, and wherein said first fluid conduit defines a linear path from said first end to said second end through said fluid mixing apparatus; a second conduit adapted to carry a secondary fluid flow, said second conduit being operatively coupled to said first conduit between said first end and said second end such that at least a portion of said second conduit is disposed around at least a portion of said first conduit so that said secondary fluid flow is directed at a first side of said first conduit and travels along a path from said first side of said first conduit around at least a portion of said first conduit before entering said first conduit; and an inlet port arrangement defined in said first conduit for communicating said secondary fluid flow from said second conduit to said first conduit, said inlet port arrangement being configured and arranged such that said secondary fluid flow alters direction before entering said first conduit and such that a size of said inlet port arrangement increases as a circumferential distance around said first conduit from said first side along said path to a second side of said first conduit opposite said first side increases.
