PitzDaily example and simpleFoam

csomerlot · September 22, 2005, 12:10

Does anyone know what the fluid is in the pitzDaily example? I used it as a template for a simpleFoam case involving water, and its not converging.

Also, I'm trying to figure out what the k, epsilon, R, and nutilda parameters are so I can find appropriate values for my fluid, are these defined anywhere?

Hi Chris,

1) the fuel of the pitzDaily example is Propane. You can see it under the combustionProperties file in the /constant directory.

2) Unfortunately i cannot help you with R and nutilda, but k and epsilon are parameters (?) related to the turbulence.

v.p.

Dear OpenFOAM users,

regarding simpleFoam/pitzDaily case, in 0 folder I got U, p, k, epsilon, nut, nuTilda, but I didn't get R???

What's the problem?

Many thanks for your helping.
