Abstract
A two-dimensional process model has been developed extending the previous one-dimensional one to study the nonlinear dynamics and stability of isothermal film casting process. The 2-D steady as well as transient numerical simulations were thus obtained employing a finite element method (FEM) along with a suitable viscoelastic constitutive equation. They have successfully revealed various nonlinear instability phenomena occurring in film casting such as beads on the film edges and the periodic instability called draw resonance exhibiting the simultaneous fluctuations of the film width and film thickness. These simulation results yield good quantitative agreement with experimental observations.
