The TIP4P/2005 model [1] is a re-parameterisation of the original TIP4P potential for simulations of water. TIP4P/2005 is a rigid planar model, having a similar geometry to the Bernal and Fowler model.

Phase diagram

The phase diagram of the TIP4P/2005 model is given in a publication by Abascal, Sanz and Vega.

and for negative pressures in the publication

Liquid-vapour equilibria

Plastic crystal phases

Recent simulations have suggested the possibility of a plastic crystal phase or phases for water.

Surface tension

The surface tension has been studied for the TIP4P/2005 model by Vega and Miguel.

Self-diffusion coefficient

The TIP4P/2005 potential has a self-diffusion coefficient, in bulk water at 298 K, of 0.21 Å2 ps−1 in a classical simulation of 216 water molecules (experimental value: 0.23 Å2 ps−1).
