I am trying to figure out the entries in thermophysicalproperties
If i look at rhoCentralFoam/forwardStep/constant/thermophysicalproperties
mixture normalisedGas 1 11640.3 2.5 0.0 0.0 1.0;
11640.3gm/mol, seems to be molecular wt of the gas
If i assume universal gas constant =8.314, and gamma = 1.4.
I can get Cp to be 2.5.
and specific gas constant to be .71424
This is consistent with a speed of sound = 1
And all seems well
If i look in rhoCentralFoam/shockTube/thermophysicalproperties i find the line
mixture air 1 28.96 1004.5 2.544e+06 0.0 1.0;
Now, 28.96gm/mol is mol. wt of air
1004.5 = Cp of air, assuming gamma =1.4
But what is 2.544e+06?
Could someone please shed some light on this?

By the way, I would like to know is there density parameter in thermophysicalProperties dictionary? Where is it?

in thermophyiscal Properties dictionary, I do not think there is any density peremeter. Only number of moles is there (red one below).
mixture air 1 28.9 1000 0 1.8e-05 0.7;
see the user guide U-177,

Has anyone tried the propeller tutorial in openFoam??
If yes let me know how to go about it.
My allrun file is not working. So iam trying to run it manually.
Can anyone help me out with the steps???
Thanks in advance.
