Authors Pavlidis M., Dimakopoulos Y., Tsamopoulos J. Abstract The one-dimensional, gravity-driven film flow of a linear (l) or exponential (e) Phan-Thien and Tanner (PTT) liquid, flowing either on the outer or on the inner surface of a vertical cylinder or over a planar wall, is analyzed. Numerical solution of the […]

Authors Georgiou G.C., Tsamopoulos J., Schultz W.W. Abstract We use finite elements and the full Newton iteration method to solve the steady, two-dimensional flow of a Newtonian planar film, issuing from a slit under a pressure difference between the two free surfaces, in the presence of gravity and surface tension.
