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.

Parameters

Phase diagram

The phase diagram of the TIP4P/2005 model is given in a publication by Abascal, Sanz and Vega [2] and for negative pressures in the publication [3]

Liquid-vapour equilibria

[4]

Plastic crystal phases

Recent simulations have suggested the possibility of a plastic crystal phase or phases for water [5] [6]

Surface tension

The surface tension has been studied for the TIP4P/2005 model [7] [8] [9]

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) [10].

Shear viscosity

The shear viscosity for the TIP4P/2005 model is 0.855 mPa.s at 298 K and 1 bar [11] (experimental value 0.896 mPa.s [12]).
