Hydrophobicity in a simple model of water: solvation and hydrogen bond energies

We explore a simple model of water: Lennard–Jones disks in two dimensions, subject to a Gaussian orientation-dependent hydrogen-bond function. The model, originally developed by Ben-Naim, shows the anomalous features of water and aspects of the hydrophobic effect. Here we further explore its phase diagram and related properties by NPT Monte Carlo simulations.
