✦ Synopsis

A simulation of planar 2D flow of a viscoelastic fluid employing the Leonov constitutive equation has been presented. Triangular finite elements with lower-order interpolations have been employed for velocity and pressure as well as the extra stress tensor arising from the constitutive equation. A generalized Lesaint-Raviart method has been used for an upwind discretization of the material derivative of the extra stress tensor in the constitutive equation. The upwind scheme has been f7(t . g)-306( er)-309(of 2(6)]TJ /T1 1 Tf 8.966 0 0 -8.966 294.009 387.893 Tm ( )Tj /F2 1 Tf

## Abstract A spherically collapsing gas bubble will create a uniaxial extension of the fluid surrounding it. This flow may be readily analyzed, and it is possible to relate observed experimental parameters such as the pressure inside the bubble and the bubble collapse rate to the predictions of vi

Internal mixers are used extensively in industry for mixing the components of rubber compounds. In these operations, in order to achieve effective mixing, the mixer chamber is always partially filled. This inevitably results in the appearance of multiple free surfaces in flow fields inside rubber mi
