Abstract

Molecular Dynamics simulations were used to measure the viscosity of a Lennard-Jones fluid. The simulation consisted of 500 type , 500 type particles, and a probe particle. An external force was applied to the probe particle and the terminal velocity was measured using curve-fitting techniques. Once the terminal velocity of the probe was known a calculation of the viscosity of the liquid was possible. The measured viscosities varied from n=0.392 ? 0.003 to n=1.04 ? 0.03. The viscosity was found to have a strong dependence on the radius of the probe and the external force. No functional dependence of the temperature of the liquid on viscosity coud be discovered.
