Lennard-Jones PVT System Model

Apr 29, 2011

The Lennard-Jones PVT System model was published as a supplemental simulation for the article "Pressure Oscillations in Adiabatic Compression" by Roland Stout in The Physics Teacher 49(5), 280-281 (2011).  The model simulates a two-dimensional system of particles confined between a thermal reservoir and a piston.   This computer model is designed to study the equation of state for particles interacting via a simple but realistic molecular potential that has a weak long-range attraction and a strong short range repulsion.   Slow-moving particles are color-coded as blue and fast particles are color-coded as yellow.  Users can set the initial particle energy, the initial particle separation, and the thermal reservoir temperature Tr.
