| Research Abstract |
Error analysis and numerical experiments are performed for conventional mixed finite element methods and pressure stabilized finite element methods of viscoelastic flow problems based on some linear and nonlinear constitutive models. When using methods of manufactured solutions, error estimates established from the mathematical justification have been numerically confirmed; when using a benchmark problem “abrupt contraction channel flow”, the numerical vortex length has been consistent with the experimental one. Therefore, the research has contributed to improvement of the reliability of numerical schemes.
