Flow modulation device for dispensing pressurized fluids

A method of controlling an output rheological state of a dispensed pressurized fluid as the fluid leaves an exit tube, the rheological state including a combination of flow rate and material phases of the pressurized fluid, and the method comprising:

• selecting the pressurized fluid and a desired output rheological state of the pressurized fluid as the pressurized fluid leaves the exit tube, wherein the pressurized fluid input rheological state is different than the output rheological state of the pressurized fluid as the fluid leaves the exit tube;
• determining a fluid pressure of the input rheological state of the pressurized fluid;
• selecting a porous element based upon the desired output rheological state of the fluid, the porous element in fluid communication with the pressurized fluid in its input rheological state and including:
• a) a material type;
• b) a pore size;
• c) a porosity;
• d) a diameter;
• and
• e) a length
• dividing, with the porous element, the pressurized fluid into a plurality of flow paths when the pressurized fluid flows through the porous element;
• controlling the flow of the pressurized fluid with the plurality of flow paths to produce a desired mass flow rate of the pressurized fluid;
• selecting the exit tube based upon the desired output rheological state of the fluid, the exit tube in fluid communication with the pressurized fluid from the porous element and including:
• f) a material type;
• g) an inner diameter;
• h) an outer diameter;
• and
• i) a length;
• and
• refocusing, with the exit tube, the pressurized fluid from the plurality of flow paths;
• selecting at least one of an alternative porous element and an alternative exit tube having at least one different parameter selected from the group of parameters a) through i) above to achieve and maintain the desired output rheological state of the pressurized fluid leaving the exit tube when the output rheological state does not match the desired output rheological state;
• and
• dispensing the pressurized fluid in the desired output rheological state based on the interaction of the elements a) through i) above.
