A simple effort using molecular beam data to compare the results of two different transient free molecule point source models was performed, motivated by a desire to determine the utility of such formulations for a variety of time-dependent applications. These models are evaluated against effusive molecular beam time-of-flight data, as well as behavior observed in pulsed laser ablation experiments and high-fidelity direct simulation Monte Carlo results. Such comparisons indicate that the physical behavior of these time-dependent expansions require taking a surface-enforced directional bias into account. This bias has been absent in a number of investigative formulations, both historical and current.
