Similarity parameter of processes near the electrode

The nature of the layers near the electrode, which occur in the case of dissipative flow of plasma in the channel of a powerful flow accelerator with a natural magnetic field, depends basically on the extent of the manifestation of the Hall effect 1, 2]. The nature of the layers nearthe electrode can be assessed according to the magnitude of the similarity parameter given below.Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 1, pp. 117–118, January–February, 1972.
