Method for three-dimensional tortuous path flow element

A method of designing a three-dimensional flow control element, the method comprising the steps of:

• digitally inserting a plurality of first computer aided designs, each being of a fixed flow configuration having a first end, a second end fixed relative to the first end, and a pair of beveled surfaces intersecting to define an apex extending longitudinally along the fixed flow configuration from the first end to the second end and continuously along at least one bend in the fixed flow configuration, into a second computer aided design of a host body such that the first and second computer aided designs define a plurality of overlapping regions representative of a plurality of arrays, each array being defined by a respective group of the plurality of first computer aided designs, each of the plurality of first computer aided designs within a given group being aligned along a first axis, the plurality of arrays being axially offset from each other with the first ends of the first computer aided designs in adjacent arrays defining a degree of overlap along a second axis perpendicular to the arrays, the plurality of first computer aided designs forming a helical arrangement wherein adjacent ones of the plurality of first computer aided designs form a helical pattern, each first computer aided design being inserted into the second computer aided design such that the fixed flow configuration extends through the host body to traverse both an inner surface and an outer surface of the host body, with at least one of the first end and the second end of the fixed flow configuration overlapping with a central bore defined by the inner surface of the host body;
• and
• subtracting the first computer aided designs and portions of the second computer aided design in the overlappingregions from a remainder of the second computer aided design to produce a third computer aided design of a flow control element having a fluid pathway extending therethrough, the fluid pathway being associated with the overlapping regions of the first and second computer aided designs.
