Modeling soot formation

[Michael Stoellinger]

Hello,

I have been using Cantera for little while now (mostly laminar
diffusion flame calculations) and I really appreciate all the effort
that went into this project. I am working on turbulent combustion and
soot formation modeling. I came across a Sandia report about CADS
(written by H. Moffat) the Cantera aerosol Dynamics Simulator. I was
very excited about this tool but I could not find the project on
sourceforge so I was wondering if CADS is not an open source project
or if I am looking at the wrong place?

I hope someone knows more about this project and could share his
information with me.

Thank you very much,
Mike

Hi,

Here is where you will find the files for Frenklach Soot Model:

http://www.me.berkeley.edu/soot/mechanisms/abf.html

http://www.me.berkeley.edu/soot/codes/soot.f

MIT Soot Model is available at:

Hello,

I am searching for CADS, too. Is there somebody, who got the files?
Alternatively I am looking for a capable soot model to predict soot emissions developed from gasoline.

On this website http://www.me.berkeley.edu/soot/ a soot model up to 4 ring aromates is mentioned, but the necessary files are not available.

With regards,
Chris

I was able to convert the Berkeley files. Code below. You shouldn't have to rename them.

>> help ck2cti
  CK2CTI - Convert a Chemkin-compatible reaction mechanism file to
            Cantera format.
 
        f = ck2cti('chem.inp')
        f = ck2cti('chem.inp', 'therm.dat')
        f = ck2cti('chem.inp', 'therm.dat', 'tran.dat')
 
     These 3 statements all create a Cantera input file 'chem.cti.' In
     the first case, the CK-format file contains all required species
     thermo data, while in the second case some or all thermo data is
     read from file 'therm.dat.' In the third form, the input file
     created will also contain transport property parameters. The
     function return value is a string containing the output file
     name.
 
 prog = [ctbin,'/ck2cti'];
 
>> f=ck2cti('abf_mech1bar.dat','abf_thermo.dat','abf_transport.dat')
f =
abf_mech1bar.cti
 
>> f=ck2cti('abf_mech10bar.dat','abf_thermo.dat','abf_transport.dat')
f =
abf_mech10bar.cti
 
>> f=ck2cti('abf_mech90torr.dat','abf_thermo.dat','abf_transport.dat')
f =

Hello again,

and thanks for this hint! I have seen this files before, but when I tried to convert them with ck2cti

ck2cti -i mech.inp -t therm.dat -tr tran.dat -id mymech > mech.cti

it doesn't work. Did you do this before?

I will try ck2cti with the files from MIT.  I wonder if I have to rename the .mech files to mech.inp? is this correct?
For example, one of the model files is called mitsootmodellowpsymp2004.mec
Is it necessary to rename it? :
ck2cti -i mitsootmodellowpsymp2004.inp -t therm. dat -tr tran.dat -id mymech > mech.cti

Regards
Chris
