DSMC simulation of overheating through atomic inelastic collisions in a metal vapour jet expansion
Description
It has been shown that in order to describe the velocity of some metal vapours (U, Gd, Ce, Ti, Cu) produced by electron beam bombardment, it is necessary to take into account the electronic-translational energy transfer. With the aim to confirm that this transfer is carried out by atomic inelastic collisions, Direct Simulation Monte-Carlo (DSMC) calculations including an atom-atom inelastic collision algorithm, are compared to experimental results on Cu and Ce vapours presented earlier. 6 figs., 6 refs
