Wormlike Micellar Fluids We chose very concentrated wormlike micellar (WM) fluids as our viscoelastic medium. WM fluids are essentially a mixture of an organic salt and type of soap or surfactant in water producing long thin tubular like structures in the water which are very weakly bound together and can heal themselves if ripped apart.

Effect of Mild Viscoelasticity in Slot Coating's Low Flow Limit In this work, the low-flow limit of slot coating of mildly viscoelastic liquids, that can be represented by Boger liquids, is examined by solving the conservation of momentum and continuity ... Low‐flow limit in slot coating: Theory and experiments ... The region of acceptable quality in the space of operating parameters of a coating process is called coating window. Their limits are set by coating defects. For the slot‐coating process the low‐flow limit is important. Operability windows in viscoelastic slot coating flows using ... Abstract. The viscoelastic-capillary model to predict approximately coating windows for the stable operations of viscoelastic coating liquids is derived using a lubrication approximation in slot coating processes. A computational study of the effect of viscoelasticity on ...
