Use gnuplot to plot graph of friction_coefficient for T3A Flat Plate case in OpenFOAM

Posted February 12, 2019 at 22:29 by purnp2

Hello,
I am new to OF and gnuplot. I am working on the T3A flat plate case in tutorials of OpenFOAM. I was struggling a lot to plot graph of friction coefficient from simulation and experimental data using the default plot_file (creatGraphs.plt) provided with the tutorial. I looked on the internet for a solution but remained unsuccessful. So, after trying for some time, I got the graph correct so I decided to share it here for use of anyone else.

The trick is we have to edit...

A generalized thermal/dynamic wall function: Part 4

Posted February 7, 2019 at 10:29 by sbaffini (NuTBox)

In previous posts of this series I presented an elaboration of the Musker-Monkewitz analytical wall function that allowed extensions to non equilibrium cases and to thermal (scalar) cases with, in theory, arbitrary Pr/Pr_t (Sc/Sc_t) ratios.

In the meanwhile, I worked on a rationalization and generalization of the framework, derivation of averaged production term for the TKE equation, etc.

While the new material is presented in a substantially different manner and will...

So for whatever reason I went on a nostalgic thought process an hour or so ago and began reading about:
The nostalgic reason for this was that I had briefly gotten a chance to work with a couple of Intel Phi Co-processors a couple of years ago and never got the time...
