Authors Poslinski A.J., Orlicki D., Tsamopoulos J.A. Abstract Inflation of an annular meniscus within a mold cavity is an important fluid mechanical problem in blow molding and glass blowing operations. Deformation of the meniscus surfaces directly affects the thickness distribution of the finished product. This paper analyzes axisymmetric inflation for […]

Authors Pelekasis N.A., Tsamopoulos J.A., Manolis G.D. Abstract It has been shown experimentally (Lee et al. 1982) that water drops with injected air bubbles inside them may be forced dynamically to assume the spherosymmetric shape. Linear analysis is unable to predict a centring mechanism, but provides two distinct modes of […]
Authors Poslinski A.J., Tsamopoulos J.A. Abstract Axisymmetric inflation of fluid annular menisci under an imposed pressure gradient is analyzed by solving the Navier-Stokes equations for velocities in the meniscus and the kinematic and dynamic conditions for interface deformation subject to surface tension forces. Numerical calculations combine Galerkin/finite-element discretization with a […]
Authors Borkar A., Tsamopoulos J. Abstract Small-amplitude oscillations of capillary bridges are examined in the limit of large modified Reynolds number. The contact line between the free surface of the bridge and the upper and lower supporting walls is allowed to undergo a restrained motion by taking its velocity to […]
