Hello
I'm trying to make a simple model: unsteady filling of tank with compressible gas
The question is how to implement the fact that porous media actually occupies volume (0.6 of it) and thus - at the end of computation mass of the gas inside the tank is actually 0.4·ρ·V but not ρ·V? I tried to define equation of state for gas: Code:
ρ(p, T) = ${ε} * ${AbsolutePressure} / 8314 * ${MolecularWeight} / ${Temperature} ∂ρ/∂p = ${ε} / 8314 * ${MolecularWeight} / ${Temperature} ∂ρ/∂T = - ${ε} * ${AbsolutePressure} / 8314 * ${MolecularWeight} / pow($Temperature, 2) |
