ABSTRACT
This chapter considers qualitatively the longitudinal-viscosity effects revealed in the presence of toroidicity of the magnetic field. It explains the approach adopted and formulates the starting equations. The role of viscosity in toroidal geometry was initially studied in the scope of the neoclassical transport theory. It has then been found that viscosity determines the plasma response on the radial electric field. The chapter examines the viscosity effect of inertia renormalization and the viscous–resistive effect. The nature of the inertia renormalization effect is not connected with resistivity. Therefore, this effect can take place in both resistive and ideal modes. Allowing for the viscosity and the resistivity simultaneously, one can reveal one more effect which is absent in the standard theory of resistive modes.
