It is also believed that applying SUPG to the optimal control problem will guarantee at most first-order accuracy in the solution [10].
We have observed that our solution methods work well whether SUPG or LPS stabilization is used.
For finite element formulation of the Stokes equations, the GLS formulation is adopted, whereas the SUPG method has been employed, for stabilized formulations of convection-dominant equations of both temperature and pseudo-concentration.
However, ff the volumetric flow rate decreases below a critical value, the suppression capability of SUPG breaks down and the solution becomes unstable.
Our solution is based on the determination that for high volume flow rates the SUPG technique with a suitably selected upwind parameter value produces oscillation free and smooth temperature profiles.
gradients do not necessarily flow along the streamline as assumed in the SU and SUPG methods.
The concept of the SUPG is to provide a heavier weight to the node upstream compared with the node downstream.
The SUPG method produces accurate and oscillation-free solutions in regions where no abrupt changes in the solution of (1.
The general approach given in [13, 23] allows to construct local projection methods, such that the discretisation stencil is not increased compared to the standard Galerkin or the SUPG approach since the approximation space [Y.
