Slot coating of mildly viscoelastic liquids

Instability in ViscoElastic Fluids | Speaking of Science A visco-elastic fluid has properties of both a liquid and a solid, while Newtonian fluids display only liquid properties. The visco-elastic fluid usedI plan to study the upstream reactions of viscoelastic fluids in the cross slot channel, at different distances from the cross, and also how active particles...

Low‐flow limit in slot coating: Theory and experiments ...

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 ... in the coating bead and the uniformity of the liquid layer are affected by the rheological properties of the liquid [1]. Until recently, coating flow research has largely been based on steady Newtonian coating flows [2–12] and their stability [13–18]. Studies related to viscoelastic coating flows have only Low-flow limit in slot coating of dilute solutions of high ... Slot coating is a common method in the manufacture of a wide variety of products. It belongs to a class of coating method known as premetered coating : The thickness of the coated liquid layer in principle is set by the flow rate fed to the die and the speed of the substrate moving past, and is independent of other process variables.
