摘要：

The effects of flow shear on the resistive wall mode (RWM) are numerically studied in a slab geometry. The reversed shear in the plasma flow has a stable effect on the linear evolution of the RWM. On the other hand, the direction of the plasma flow has an effect on the stabilization of the RWM. The field-aligned flow exhibits the strongest suppressing effect. The RWM saturates in the nonlinear phase. The saturation level decreases with increasing of shear rate s. The saturation can be attributed to flux piling-up on the resistive wall.
