Abstract
A fluid flow stabilizer which includes two pluralities of stabilizer units adjacent one another. Each unit includes a plurality of parallel axially extending tubules. The units are movable into different relative positions so that certain of the tubules of a unit are aligned in fluid communication with tubules of another unit. Index means are provided for fixing the units in different selected relative positions.

Fluid flow stabilizing apparatus comprising:
- primary means defining a primary fluid flow path;
- first and second stabilizer units located adjacent one another in the primary flow path and including, respectively, a plurality of parallel, axially extending first tubules, and a plurality of parallel, axially extending second tubules parallel to the first tubules, the stabilizer units being movable into different relative positions in which certain ones of the first and second tubules are located in alignment and in fluid communication, and the others of the first and second tubules are out of alignment and thereby out of fluid communication
- index means for fixing the stabilizer units in a selected one of the different relative positions thereby to select a desired number of aligned first and second tubules having a length-to-EHR ratio high enough to assure laminar flow of a fluid therethrough.
Fluid flow stabilizing apparatus comprising:
- means defining a fluid path;
- a plurality of circularly configured stabilizer units located in coaxial relation in the fluid flow path and including, respectively, pluralities of parallel, axially extending and straight tubules, the stabilizer units being rotatable relative to each other of the tubules of the respectable stabilizer units are in alignment and fluid communication, and the remainder of the tubules, are out of alignment and thereby out of fluid communication;
- and
- index means for fixing the stabilizer units in a selected one of the different rotated positions thereby to select a desired number of aligned tubules having a length-to-EHR ratio high enough to assure laminar flow of a fluid therethrough.
