The Intramolecular Pressure and the Extension of the Critical Point’s Influence Zone on the Order Parameter

Figure 5

Profiles of the contributions to the normal (left) and tangential pressures (right), for ethane in the VLE as a function of the simulation cell position in the inhomogeneous direction of the simulation cell. The color code in (a)–(f) represents results at 100 K (black), 140 K (green), 220 K (blue), and 260 K (red). Kinetic contributions are shown in (a) and (b), while intramolecular and intermolecular contributions are shown in (c), (d), and (e) and (f), respectively.
