Hello,
Could anyone help me find out where combustion properties are located in fireFoam? I am using oppositeburningpanels and can see that C3H8 has been used, and I do not seem to be able to find how they calculate or specify the heat released by combustion. I also found a properties section for C3H8 in doxygen, it specifies rho, cp, and other things but not heat released. Thanks |

Cp combustion seems to be specified with cp polynomial coefficients in thermo.compressiblegas, then using enthalpy of different products before and after the reaction to get heat released.
Ok, so I have now found that varliable dQ specifies the heat released (in J), however I need to try and sum this value over each cell in the volume to get the total heat release rate. Does anyone know how to do this in paraview? I have tried integrate variables, but that seems to only give me values for a single cell. Exporting the grid to excel and summing all dQ values works, but it is quite a slow process. Thanks, Toby |
