Information

This model is used to compare the curvatures of two sub-critical isotherms in the two-phase region of a p,d-plot.
One isotherm is calcualted directly from the EoS (showing some loops in the two-phase region),
one isotherm is calculated taking into account the VLE conditions (straight line in the two-phase region).
How to use:
  1. Simulate with T<T_crit
  2. Plot p and state.p
  3. Make d the independent variable of the plot
  4. Rescale the range for p to something like -100 to +100
  5. Look at the loops
