The axisymmetric visco-resistive magnetohydrodynamic steady states allowing flows (i.e. non-vanishing velocity fields) are computed for a toroidal JET-like geometry. It is shown that a spatially inhomogeneous heating of moderate magnitude leads to an increase of typical toroidal speeds with respect to the situation with uniform temperature with identical mean Hartmann numbers. A symmetry argument is introduced to capture the symmetry breaking, induced by the temperature gradient, that produces a net toroidal plasma flow.

具有不均匀加热的托卡马克等离子体粘阻磁流体动力学模型中的稳态流动

计算允许流动的轴对称粘阻磁流体动力学稳态（即非消失速度场）用于环形JET 几何。结果表明，相对于具有相同平均哈特曼数的均匀温度的情况，中等量级的空间不均匀加热导致典型的环形速度增加。引入了一个对称参数来捕捉由温度梯度引起的对称性破坏，从而产生净环形等离子体流。
