Hi,
I am modeling in chtMultiRegionFoam and i am confused with solidThermophysical properties and Thermophysical properties folders. here are two of folders, at first consider solidThermophysical properties folder : { //- thermo properties rho rho [1 -3 0 0 0 0 0] 2500; Cp Cp [0 2 -2 -1 0 0 0] 750; K K [1 1 -3 -1 0 0 0] 1.4; //- radiation properties kappa kappa [0 -1 0 0 0 0 0] 0; sigmaS sigmaS [0 -1 0 0 0 0 0] 0; emissivity emissivity [0 0 0 0 0 0 0] .88; //- chemical properties Hf Hf [0 2 -2 0 0 0 0] 0; } what are kappa and simaS and Hf? what is the Hf's unit? and here is one of thermophysical properties folder: mixture { specie { nMoles 1; molWeight 28.97; } thermodynamics { Cp 1007.526; Hf 0; } transport { mu 1.908068e-05; Pr 0.705159; } What are the units of Cp , Hf , mu ? Regards |

They are all in the International System of units. The user guide helps you a little.
