Report
The Results - Report tab shows the approximation of Forchheimer’s equation that fits the entered velocity / pressure drop pairs. The first coefficient approximates:
The second coefficient approximates:
In this example, the estimation of the velocity for the given Experiment Input and a pressure drop of is .
Post-Processing
Several post-processing options are available for the Forchheimer Approximation result on the left section of the Result Viewer. Change the parameters Thickness of media for prediction, Density of fluid used for prediction and Viscosity of fluid used for prediction described with the other Predicted Experiment options. Click Apply to change the plot and report of the result file. In the example below the Thickness of media was changed from 0.001 m to 0.002 m.

Important! Note that after clicking Apply, the result file changes and is not the original simulation result file anymore! If Back-up result file is checked, the original *.gdr file is saved in the result folder and can be restored at any time. |
Additionally, a Velocity list or a Pressure drop list can be given for prediction. Select one of the two and enter a comma-separated list of values and click Apply. In the example below, the pressure drop list was expanded by the value 400.
The graph can also be plotted with interchanged axes by checking Velocity – Pressure drop and clicking Apply.
