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. Model elastic liquids with water‐soluble polymers - Dontula ... Model liquids with nearly constant viscosity and adjustable elasticity are needed to resolve the role of elasticity in coating and other free‐surface flows. Available Boger liquids are not well suited to free‐surface flows, because they are solutions in organic solvents and their viscosities exceeding 1 Pa · s fall on the high side.
