Abstract

Mathematical modelling was applied to study the dynamical and physical properties of the supersonically expanding rare gas plasma formed by a cascaded arc. Keeping constant the volume flow rate and the power input into the plasma, the Ne, Ar and Xe flows are compared. We demonstrate that the difference in mass flow rate affects the dynamic properties of plasma expansion. Modelling and experimental results show that the recombination heating of electrons is more significant in a gas that has a lower ionization potential.
