Vs. Tsypin et al., Effect of plasma subsonic toroidal flows induced by Alfven waves on transport processes in the edge of elongated tokamaks, BRAZ J PHYS, 31(1), 2001, pp. 34-41
There is a renewed interest in using Alfven waves (AW) in tokamak plasmas.
Previously, AW were actively explored mostly for current drive and plasma h
eating in tokamaks. Presently, the possibility of the anomalous and neoclas
sical transport suppression by AW in tokamak plasmas is being vividly discu
ssed. AW can also induce poloidal and toroidal plasma rotation. Toroidal pl
asma rotation can reach the subsonic level. These flows can substantially a
ffect neoclassical transport both in collisional and weakly collisional pla
smas. In this paper, the effect of plasma subsonic toroidal flows induced b
y Alfven waves on transport processes in the edge of elongated tokamak is i
nvestigated. The dependence of poloidal plasma rotation and ion heat conduc
tivity on the elongation parameter and the ratio of induced toroidal veloci
ty to the sonic speed are analytically obtained.
