Application of the Finite Piece Method to Simulate Viscoelastic Fluid Flows in L-Shaped Channel

Abstract:

The finite piece method is established to solve the flows of K-BKZ fluid in L-shaped channel. Numerical results are given to compare to the three-dimensional simulation using the finite element method (FEM). It is found that the results are highly consistent as a whole. The error of flow distribution is smaller than 2% at the outlet. There is a minor discrepancy of the pressure in the convergence region of channel but they are restricted to a small region. The present approach demonstrates its superiority over the conventional FEM for analyzing slit flow.
