Navier-Stokes

Single-phase Navier-Stokes flow. More...

Description

A single-phase, isothermal Navier-Stokes model.

This model implements a single-phase, isothermal Navier-Stokes model, solving the momentum balance equation

\[ \frac{\partial (\varrho \textbf{v})}{\partial t} + \nabla \cdot (\varrho \textbf{v} \textbf{v}^{\text{T}}) = \nabla \cdot (\mu (\nabla \textbf{v} + \nabla \textbf{v}^{\text{T}})) - \nabla p + \varrho \textbf{g} - \textbf{f} \]

By setting the runtime parameter Problem.EnableInertiaTerms to false the Stokes equation can be solved. In this case the term

\[ \nabla \cdot (\varrho \textbf{v} \textbf{v}^{\text{T}}) \]

is neglected.

The mass balance equation

\[ \frac{\partial \varrho}{\partial t} + \nabla \cdot (\varrho \textbf{v}) - q = 0 \]

closes the system.

The Navier-Stokes model can be extended to a Darcy-Brinkman model by adding the term:

\[ + \epsilon_B \mu \mathbf{K}^{-1} \mathbf{v} \]

to the momentum balance. This can be achieved with the helper function addBrinkmanTerm. The function relies on the spatial parameters class being based on BrinkmanSpatialParams or providing the brinkmanEpsilon and inversePermeability interfaces. These interface functions provide the weighting factor \( \epsilon_B \) and the permeability tensor \( \mathbf{K} \).
