Multi-field coupling in the scrape-off layer of tokamak plasma
We study a reduced electrostatic fluid model for the tokamak scrape-off layer, which incorporates temperature gradient and vorticity gradient as two free energy fields.Two scenarios of field coupling are addressed: (1) sheath condition; (2) product vortex wave coupling.For the sheath condition induced field coupling, the poloidal $mathbf{E} imes m
