Stabilized finite element methods for the velocity-pressure-stress formulation of incompressible flows Nonlinear model

摘要

Formulated in terms of velocity, pressure and the extra stress tensor, the incompressible Navier-Stokes is discretized by stabilized finite element method. The stabilized method proposed is analyzed for the full nonlinear model, and is applicable to various combinations of interpolation functions, including the simplest equal-order linear and bilinear elements.
