(369j) Effect of Elasticity on Stability of Viscoelastic… Curtain coating is one the preferred methods for high-speed precision application of single-layer and multi-layer coatings in industry.The rheological characteristics of the coating liquid play an important role on these mechanisms, but the fundamental understanding of the role of rheology is still... 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.Although most of the liquids coated industrially are polymeric solutions and dispersions that are not NewtonianAt the concentration level of the high molecular weight polymer explored here, the viscoelastic behavior of... Viscoelastic solution - Big Chemical Encyclopedia Fano columns are most easily formed in viscoelastic solutions where extensional viscosities exceed shear viscosities by several orders of magnitude.The simplest mechanical model which can describe a viscoelastic solution is called Maxwell element. It consists of a spring and a viscous element...

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 . 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.
