Lennard-Jones PVT System Model for Windows v.1.0

The Lennard-Jones PVT System 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. The thermal conductivity parameter ? determines the probability that a collision with the thermal wall will affect (thermalize) the colliding particle. If the conductivity is one, the particle velocity after a reservoir collision is set according to Maxwell-Boltzmann statistics. If the conductivity is zero, all reservoir collisions are elastic and the total internal energy E of the system is conserved. The piston input fields in the bottom panel are used to compress and expand the system. Users can approximate an adiabatic compression by setting ?=0 and can approximate an isothermal compression by setting ?=1. The piston speed must, of course, be small to insure that the system remains in equilibrium during the compression for a (quasi-static approximation) reversible process. Separate windows allow users to follow the change in state of the system on a PV plot or a time evolution plot.The Lennard-Jones PVT System was developed using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_stp_md_LennardJonesPVTSystem.jar file will run the program if Java is installed.
