Abstract
Fluid dynamic results of an under-expanding argon plasma expanding from a cylinder symmetric arc, a high density source with small dimensions, into a low pressure vessel with large dimensions are presented.
The influence of different boundary jet geometries on the flow parameters and on recombination is examined by use of a plasma fluid model which can adapt the jet geometry. The fluid model is a radially integrated one-dimensional non-local thermal equilibrium model, which uses results from the gas dynamic theory of Prandtl - Meyer.
