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.


Temperature of maximum density[edit]

See: a table of water TMD values.

Liquid-liquid critical point[edit]

The ST2 model has a liquid-liquid transition [2]. Liu, Panagiotopoulos, and Debenedetti [3] have located the critical point of the liquid-liquid transition of the ST2 model [4] to be at a temperature of , a density of and a pressure of . This finding is supported in the work of Sciortino, Saika-Voivod and Poole [5].
