Static shapes of levitated viscous drops

  title={Static shapes of levitated viscous drops},
  author={By L. DUCHEMIN and J. R. L ISTER and Ulrich Lange},
We consider the levitation of a drop of molten glass above a spherical porous mould, through which air is injected with constant velocity. The glass is assumed to be sufficiently viscous compared to air that motion in the drop is negligible. Thus static equilibrium shapes are determined by the coupling between the lubricating pressure in the supporting air cushion and the Young–Laplace equation. The upper surface of the drop is under constant atmospheric pressure; the static shape of the lower… CONTINUE READING
