Ah, ok. Right now I finally found these books in our University Library. So I'm now going to see if they exist also in reality :-)

I have a small perl-script to help me in this that
you might want to use

http://files.nequam.se/liquidProperties.tgz

the units in the NSRDS tables are per mole and not per kg, so some coefficients needs to be recalculated.

there is an example file for water that shows you how its done.
to create the foam .C and .H files just run
./nsrds2foam.pl props.water

Hi Niklas,

Another thing...
Since you are still into combustion research (as far as I know/imagine) I have another question to you; in your PhD you mention that "a practical Eulerian treatment of the spray [...] will not be realizable for some time." According to another thread (http://www.cfd-online.com/OpenFOAM_D...tml?1213613536),
I'm interested if it is now possible to simulate combustion using Euler-Euler methods?

Best regards,
Andreas

Im currently looking into the ELSA approach.

Back to the original topic of NSRDS functions and adding liquids...

Today I managed to order the "Data compilation tables of properties of pure compounds" to our TU library

What I'm thinking about now is:
Will it be possible to add solid molecules instead of liquid ones or am I then going to run into conflicts concerning atomization an break up for example?

Coupling Vaporization Model with the Eulerian ....
Lebas, et al.

SAE 2003-01-0005
A 3D Eulerian Model to Improve the Primary Breakup of Atomizing Jet
Blokkeel, et al.

Numerically, its all about Reynolds and Weber numbers so it doesnt matter if its solid or liquid, as long as surface tension, density, viscosity exist and produce usable number.
And you can always turn off any model you dont need.

Thank you very much for the references!

The reason for me asking if it is possible to include solid molecules is that in your example of H2O and the according "props.water" file all the coefficients for the solid properties are omitted (e.g. solid heat capacity).

How can I add these values for example if I want to create the foam .C and .H files for NaCl?

solid properties have been omitted from the 'liquids'.

If you still would like to use it I suggest you just replace the heat capacity with the solid heat capacity. etc.

It doesn't seem to be that easy to implement solids using your pearl script...

I'm running into the error "Equation for latent heat of evaporation is not implemented yet."
Could you please help me out!?

It's the equation for Heat of Vaporization.
For water it is "solved" using NSRDS function 106 (4 coeeficients).
For NaCl it is "solved" using NSRDS function 100 (only 1 coefficient given).

It seems like that's the problem...

Now that the problem is solved, I add NACL to the liquids directory and run "wmake libso".
At first it looks quite promising;
'dependency list for source file NACL/NACL.C' is made and '~/OpenFOAM/OpenFOAM-1.4.1/lib/linux64GccDPOpt/libliquids.so' is updated.

But when I try to run my case a FATAL ERROR occurs: Unknown liquid type NACL

why is that???

You need to add
NACL/NACL.C
to the src/liquids/Make/files file

then you can run 'wmake libso'

anyhow, that doesn't work either.
I recompiled the three directories in the lagrangian subdirectory and also the dieselFoam solver.
But NACL is still unknown.

Do you have any further hints?

Thanks a lot Mr. Nordin for this post, I'm using Perry's handbook for determine the properties, did you have any other suggest?
Thanks a lot
Kind regards
