Systems and methods for restricting movement in flexible ducts

Abstract:

Methods and systems for restricting movement in a flow mixer including a plurality of lobes that each includes a trough, using a stiffener mechanism, are provided. The stiffener mechanism includes a first end portion configured to be coupled to a first lobe of the plurality of lobes and a second end portion configured to be coupled to a second lobe of the plurality of lobes. The stiffener mechanism also includes a body portion coupled between the first end portion and the second end portion such that the body portion is configured to restrict movement of the first and second lobes.
