Molecular dynamics of a Lennard-Jones liquid undergoing a homogeneous adiabatic expansion provides a direct numerical simulation of the atomization process. Results from a symmetric-triaxial expansion appear to be consistent with the mean droplet size found in the Knuth and Henne free-jet experiments. New simulations with axisymmetric expansions, similar to flow through an orifice, show only small departures from the symmetric expansion results.
