Moving Boundaries VII. Forward Roll Coating Flows Of Viscoelastic Liquids .For Newtonian liquids, the stability of the film-split flow is determined by the competition of capillary forces and viscous forces: the onset of meniscus nonuniformity is marked by a critical value of the capillary number.

COATING • Viscoelasticity dominates, then time dependent stress • Time is greater at lower temperatures. Viscoelasticity - Wikipedia Unlike purely elastic substances, a viscoelastic substance has an elastic component and a viscous component.Specifically, viscoelasticity is a molecular rearrangement. When a stress is applied to a viscoelastic material such as a polymer, parts of the long polymer chain change positions.
transient velocity and pressure profiles inside the die have been compared for the patch slot coating applications. As the second case, flow dynamics of both Newtonian and non-Newtonian liquids in patch slot coating mode has been focused for its optimal process design. Coating liquids are intermittently coated on
