Steady finite-Reynolds-number flows in three-dimensional collapsible tubes

  title={Steady finite-Reynolds-number flows in three-dimensional collapsible tubes},
  author={Andrew L Hazel and Matthias Heil},
A fully-coupled, finite-element method is used to investigate the steady flow of a viscous fluid through a thin-walled, elastic tube mounted between two rigid tubes. The steady, three-dimensional, Navier–Stokes equations are solved simultaneously with the equations of geometrically-non-linear, Kirchhoff–Love shell theory. If the transmural (internal minus external) pressure acting on the tube is sufficiently negative then the tube buckles non-axisymmetrically and the subsequent large… CONTINUE READING
