Molecular dynamics simulation of sub- and supercritical water with a new interaction potential

A molecular dynamics experiment was performed for water under sub- and supercritical conditions with a new interaction potential including the nonelectrostatic H-bond component. The internal energy, self-diffusion coefficient, mean number of H-bonds per water molecule, and distributions of molecules according to the number of H-bonds were calculated over a wide temperature range at pressures of 50 and 100 MPa. The temperature dependences of these properties were analyzed.
