Since liquids are normally incompressible, an increase in pressure doesn't really bring the molecules significantly closer together. Simple models of molecular interactions won't work to explain this behavior and, to my knowledge, there is no generally accepted more complex model that does. Flow of Oldroyd-B Viscoelastic Fluid Many complex fluids of interest exhibit a combination of viscous and elastic behavior under strain.The Oldroyd-B fluid presents one of the simplest constitutive models capable of describing the viscoelastic behavior of dilute polymeric solutions under general flow conditions.

The e ect of shear-thickening on the stability of slot-die ... The e ect of shear-thickening on the stability of slot-die coating Sunilkumar Khandavallia, Jonathan P. Rothstein;a aMechanical and Industrial Engineering, University of Massachusetts Amherst, MA 01003 USA Abstract Slot die coating is an economical roll-to-roll processing technique with potential to revolutionize the fabri- The Effects of Viscoelastic Behavior on Coating - AIMCAL Coating rubber bands is not easy. So when you look at coating liquids that have molecules already formed, or the fluid has a rubbery nature, care needs to be taken to conisder the effects of viscoelastic behaviour. Viscoelasticity is the fluid’s reaction to being deformed both in viscosity and elasticity. Simulation of Coating -Visco-Elastic liquid in the Mico-Nip ...
