Static mixer for fluids

A static mixer, comprising:

• a hollow body having defined therein:
• a first fluid inlet port for introducing a first fluid along a centerline axis of the hollow body;
• a second fluid inlet port for introducing a second fluid along the centerline axis of the hollow body downstream of the first fluid inlet port;
• and
• a fluid outlet downstream of the first and second fluid inlet ports;
• and
• a first mixing structure positioned between both the first and second fluid inlet ports and the fluid outlet, the first mixing structure including:
• a first restrictor structure in the hollow body, the first restrictor structure having a cross-axis area that is smaller than a cross-axis area of the hollow body;
• a first diverter having an at least frustoconical shape and positioned downstream of the first restrictor structure;
• and
• a first support coupled to the first diverter and the hollow body to align the first diverter with the centerline axis of the hollow body wherein the first support includes a plurality of structural members coupled to a wall of the first diverter and to an interior surface of the hollow body;
• and
• wherein the second fluid inlet port introduces the second fluid along the centerline axis upstream of the first restrictor structure.
