ABSTRACT:
An improved laminar flow elbow system and method wherein the elbow system comprises a straight pre-pipe section to define the flow path of a fluid; the pipe section included directly prior to the inlet of a curved pipe section and having and comprising a plurality of vanes to impart a rotation to the fluid before passing through a curved pipe section to provide a generally flat velocity profile at the exit of the curved pipe section and to minimize turbulence of the fluid as it passes through the curved pipe section, and a substantially straight post-pipe section to define a flow path exit pipe section included directly at the exit of the curved pipe section, and containing a plurality of vanes to impart a backward rotation movement to the fluid flow from the exit of the curved pipe section, to substantially terminate rotation of the fluid upon exiting from the straight pipe section without substantial deterioration of the flatness of the fluid velocity profile and without generating substantial amounts of turbulence.
