Effect of the contraction ratio upon viscoelastic fluid flow in three-dimensional square-square contractions [PDF]
, 2011 In this work we investigate the laminar flow through square–square sudden contractions with various contraction ratios (CR¼2.4, 4,8and12), using a Newtonian fluid and a shear-thinning viscoelastic fluid.

Numerical solution of the eXtended Pom-Pom model for viscoelastic free surface flows [PDF]
, 2011 In this paper we present a finite difference method for solving two-dimensional viscoelastic unsteady free surface flows governed by the single equation version of the eXtended Pom-Pom (XPP) model. The momentum equations are solved by a projection method

Exponential Energy Decay of Solutions for a Transmission Problem With Viscoelastic Term and Delay
Mathematics, 2016 In our previous work (Journal of Nonlinear Science and Applications 9: 1202–1215, 2016), we studied the well-posedness and general decay rate for a transmission problem in a bounded domain with a viscoelastic term and a delay term.

Mechanics of Viscoelastic Thin-Walled Structures [PDF]
, 2013 Thin-walled structures made of polymers and reinforced polymer composites are prominent candidates for constructing large lightweight structures. A major challenge in designing polymer-based thin-walled structures is their time and temperature dependent ...

Blow-up of solutions to a viscoelastic parabolic equation with positive initial energy
Boundary Value Problems, 2017 In this paper, a semilinear viscoelastic parabolic equation with nonlinear boundary flux is studied. Due to the comparison principle being invalid, potential well method and concavity argument are used to prove that the solutions blow up in finite time ...

Viscoelastic properties of crystals [PDF]
The Journal of Chemical Physics, 2009 We examine the question of whether fluids and crystals are differentiated on the basis of their zero frequency shear moduli or their limiting zero frequency shear viscosity. We show that while fluids, in contrast with crystals, do have a zero value for their shear modulus, in contradiction to a widespread presumption, a crystal does not have an ...
