Patent ID: 8432057

Claim:
A fluid transporting apparatus for transporting a first fluid, comprising: a polygonal tube comprised of flexible walls enclosing a first fluid passage and having a polygonal cross-section, with a plurality of tube edges corresponding to corners of the polygonal cross-section; a plurality of flexible ribbons, each having a first longitudinal edge, a second longitudinal edge, and a contact surface, wherein each of the plurality of flexible ribbons is connected along the first longitudinal edge to one of the plurality of tube edges, and wherein the contact surface projects transverse to a longitudinal axis of each of the plurality of flexible ribbons, the longitudinal axis being oriented substantially parallel to a primary flow direction of a flowing second fluid, and the contact surface being disposed in contact with the flowing second fluid; at least one deformation retaining component connected to one of the first longitudinal edge and the second longitudinal edge of at least one of the plurality of flexible ribbons; at least one base member fixed with respect to the flowing second fluid and connected to the at least one deformation retaining component; and wherein dynamic undulations of the plurality of flexible ribbons caused by the flowing second fluid impart forces via the flexible walls of the polygonal tube to a first fluid inside the first fluid passage to transport the first fluid along a longitudinal axis of the first fluid passage.
