In this paper, we consider viscoelastic stresses T 11 , T 12 and T 22 arising in the stagnation flow of a dilute polymer solution; in particular, we consider an upper convected Maxwell (UCM) fluid. We present exact solutions to the coupled partial differential equations describing the viscoelastic s
We consider stagnation point flow away from a wall for creeping flow of dilute polymer solutions. For a simplified flow geometry, we explicitly show that a narrow region of strong polymer extension (a birefringent strand) forms downstream of the stagnation point in the UCM model and extensions, like
A systematic framework introduced recently to obtain parameter-free predictions of material properties of dilute polymer solutions in extensional ows is reviewed. The essential constraint of ensuring that the model polymer molecule has a ΓΏnite length is met by using a bead-spring chain model with ΓΏn
