Abstract
This paper investigates the scaling of asymmetric wall force and toroidal rotation during tokamak disruptions. It is shown by simulations and analysis how these effects depend on the displacement in an asymmetric vertical displacement event (AVDE) and on 3D magnetic field perturbation amplitude. The simulations include a sequence of both upward and downward displacements. It is verified that the asymmetric force is proportional to the vertical current moment, which in turn is proportional to the product of vertical displacement and the magnetic perturbation amplitude. It is verified how the scaling of toroidal rotation in AVDE disruptions depends on magnetic perturbation amplitude, vertical displacement, and βN.
