Abstract
In this work, we present high-resolution solutions for viscoelastic 4:1 planar contraction flow problems using a transient finite element
method based on the fractional step method (FSM) and stabilization techniques (DEVSS-G/DG) with linear equal-order interpolation function.
The Oldroyd-B model was used as the constitutive equation. A parallel multi-frontal algorithm was implemented to enhance computational
speed and all solutions were obtained on a parallel machine. The vortex intensity and the re-attachment length of corner vortex show good
mesh-convergent behavior and are compared with previous results from the literature. In particular, the present results are in good agreement
with the predictions of the high-resolution finite volume method of Alves et al. [15]. This may be the first case that quantitative agreement
is obtained between studies using different numerical methods for the benchmark problem of 4:1 planar contraction flow. As there has been
little quantitative a
