ST2 is a model for simulations of water [1]. The ST2 model is based on the earlier Ben-Naim and Stillinger model, known as the BNS model.
Parameters
Temperature of maximum density
See: a table of water TMD values.
Liquid-liquid critical point
Liu, Panagiotopoulos, and Debenedetti [2] have located the critical point of the liquid-liquid transition to be at a temperature of , a density of and a pressure of .
