Abstract Precise molecular dynamics calculations on molten potassium chloride have been performed using Born-Mayer-Huggins pair potentials and periodic boxes containing 216 ions. It is found that the function (2 Ek - ψ)/3V, Ek being the kinetic energy, the instantaneous virial and V the volume, respectively, which on averaging yields the pressure, fluctuates by ± 2000 bar due to the fluctuations of the exponential term ψex of ψ .To base the calculated pressure and velocity auto-correlation functions on good statistics, it seems necessary to reduce these fluctuations by increasing the periodic boxes.

We propose a new approach to the study of friction in molecularly thin films. The instantaneous occurrence of both momentum and thermal kinetic energy diffusions in the film requires a sophisticated energetic approach. This can be done by identifying the energetic terms which are due to thermal agitation or shearing rather than globally thermostating the system. With this approach, it becomes possible to quantify the energy loss due to friction and to describe the local mechanisms of its dissipation inside the liquid and through the interfaces. Implemented, the method can give more accurate results in molecular dynamics simulations of confined films.
