Experimental study of enhanced flow asymmetry due to viscoelasticity: An assessment of viscoelastic constitutive models

Flow past an asymmetrically confined cylinder of shear-thinning viscoelastic polymer solutions has been experimentally investigated. We show that the flow asymmetry induced by the asymmetric geometry is enhanced at Weissenberg numbers (Wi) above unity; that is, the flow in the no...
