combustion related transportProperties.file in openfoam v6.0
 

Hello,guys:
I am working on some numerical simulation about combustion using openfoam. In the combustion/tutorials/reactingFoam/RAS/SandiaD_LTS/constant/thermo.compressibleGasGRI file, for each species there are two transport paremeters:
OH
{
specie
{
molWeight 17.00737;
}
thermodynamics
{
Tlow 200;
Thigh 3500;
Tcommon 1000;
highCpCoeffs ( 3.09288767 0.000548429716 1.26505228e-07 -8.79461556e-11 1.17412376e-14 3858.657 4.4766961 );
lowCpCoeffs ( 3.99201543 -0.00240131752 4.61793841e-06 -3.88113333e-09 1.3641147e-12 3615.08056 -0.103925458 );
}
transport
{
As 1.512e-06;
Ts 120;
}
elements
{
O 1;
H 1;
}
}
I am confused by the meanings of transport parameters As and Ts
Are these parameters used in the sutherland's law for calculation of viscosity. But the there parameters I got through Google should be 1.458E-06 and 110.4, which are different with that in the openfoam file.
Is there anyone could help me comprehend this issue?
Are they same or different?
Thanks very much!!:):):)
