Tools for computing thermodynamic properties of molecular fluids

Project description

mol-TDN: Thermodynamic properties of molecular fluids

Examples

  • Compute density of methane at 100 bar using the Peng-Robinson equation of state:
from mol_tdn import Molecule, compute_eos, plot_pv
m = Molecule('methane')
m.info()

    Molecule: methane
        Chemical formula: CH4
        Molecular Mass: 16.0 g/mol
        Critical Temperature: 190.56 K
        Critical Pressure: 45.99 bar
        Accentric factor: 0.012

compute_eos(m, t=298, p=100, eos='pr')
