# Test Case for inducedTurbulence fvModel

## Description

Copy of the release bubbleColumn tutorial
(tutorials/multiphaseEuler/bubbleColumn) but changed such that turbulence is
only solved for the water phase rather than using a mixture model. The case
features phase inversion so it needs the addonPhaseTurbulenceStabilisation
fvModel as well. Given that turbulence should only be induced where there is air
dispersed in water, this case should show an increase of turbulent kinetic
energy and dissipation rate only in the volume where water is the continuous
phase. The blending is reimplemented in the corresponding fvModel but looks into
the `blending` dictionary of `${FOAM_CASE}/constant/phaseProperties`. So this
test checks the functionality of blending of the induced turbulence.

## Technical Information

Identical to release tutorial `tutorials/multiphaseEuler/bubbleColumn` except

- turbulence equations only solved for water phase
- simulated physical time is 3s

## Pre-Processing

Identical to release tutorial `tutorials/multiphaseEuler/bubbleColumn`.

## Post-Processing

The Gnuplot script `createGraphs` is located in the `validation/` directory and
it plots the time-averaged turbulent kinetic energy along the column y-axis.
