  • Acoustic management of fluid flow within a duct
    Patent number: 8061477
    Abstract: Apparatus and methods described herein provide for the management of noise associated with a duct. A sound-dampening apparatus is provided consisting of a duct through which a fluid flows, such as an air duct. A flexuous cord is helically wound around the inner or outer surface of the duct at a pitch corresponding to a selected acoustical frequency range associated with the fluid flow through the duct.
    Type: Grant

  • Apparatus and method for generating air stream
    Patent number: 5713212
    Abstract: An apparatus for generating an air stream that is substantially-columnated about a given axis includes a converging-diverging nozzle, a manifold in fluid communication with the nozzle, and a compressor supplying a quantity of compressed air to the manifold to induce a first air flow through the nozzle. The first air flow is characterized by sonic flow at the nozzle throat and supersonic flow at the nozzle exit. The supersonic first air flow exiting the nozzle is directed into one end of an elongate tube. The thus-directed first air flow induces a second flow of ambient air into the one end of the tube. The first air flow mixes with the second air flow within the tube and exits as an air stream that is substantially columnated about the axis of the tube.
