Recent Advances on a Stable Hybrid Finite Elements Methodology for Stokes Flow using H(div) Spaces
Resumo
The motion of an incompressible flow can be accurately described by the Navier-Stokes equations. When the viscous forces have a greater influence compared to the convective ones, eg: creeping flows, the governing equations can be simplified to the linear Stokes equations. Moreover, the flow is said to be in a steady state if the magnitude of the inertial forces is much smaller than the other terms, thus not varying its velocity in time. [...]
