Hey
I am using OpenFOAMv8. I have a natural ventilation setup where I want to model the concentrations of CO2. I am unsure whether I have correctly setup the CO2 boundary condition file. I have an inlet sources that represent people breathing. I want the CO2 source at this inlet to be 5% of the air entering into the model. I also want their to be a background CO2 concentration of 400ppm. As the CO2 BC file has no dimensions I tried to set the CO2 sources as a proportion hence why i have put a value of 0.05 for the inlet and 0.0004 for the internalField. Does anyone know if my current CO2 BC file is correct? Regards Code:
FoamFile { version 2.0; format ascii; class volScalarField; location "0"; object inback_CO2; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 0 0 0 0 0 0]; internalField uniform 0.0004; boundaryField { "xmin|xmax|ymin|ymax|zmax" { type inletOutlet; inletValue $internalField; value $internalField; } Inlet { type inletOutlet; inletValue uniform 0.05; value uniform 0.05; } "zmin|Ceiling|Floor|East_Wall|North_Wall|South_Wall|West_Wall|Computer01|Person01|Computer02|Person02" { type zeroGradient; } #includeEtc "caseDicts/setConstraintTypes" } // ************************************************************************* // |
