The object of this paper is the study of a cylinder sym. plasma expansion from a high d. source with small dimensions into a low pressure vessel with large dimensions. The gas dynamic theory of Prandtl-Meyer flows is used as a guide to get a better understanding of the flow behavior of the expanding plasma. In gas dynamics, the expansion from the exit pressure to the background pressure takes place through a series of expansion waves just beyond the arc and is followed by a normal shock. A plasma behaves similar. Using gas dynamic theory, the shock position and the Mach no. at the shock have been estd. for an argon plasma. Further, with the help of control vols. we estd. the cross-section of the normal shock. [on SciFinder (R)]
