Darcy - Brinkman Example
Model ID: 609
This example model characterizes a transition in flow regimes: slow flow in porous media quickens to a perforation in a well casing and ultimately moves into and up the well. Darcy’s law describes flow velocities at a distance from the well. Closer to the perforation the Brinkman equations apply. Movement of fluid in the well is described by the Navier Stokes equations. This example starts with a model that couples Darcy’s law with the Brinkman equations and the Navier Stokes equations (in the wellbore) to produce a fully coupled simulation for three different flow laws.
