Description

Single-phase Navier-Stokes flow.

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

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

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

$\nabla \cdot (\varrho \textbf{v} \textbf{v}^{\textup{T}})$

is neglected.

The mass balance equation

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

closes the system.

So far, only the staggered grid spatial discretization (for structured grids) is available.
