Abstract

We report the results of the experiments on the suppression of the MHD instability in a model of the aluminium reduction cells. The idea behind the study is to introduce obstacles in the liquid metal to suppress the propagation of the rolling-pad instability wave. As a result, in some configurations with obstacles we detect lowering of the wave amplitude, reduction of its propagation speed and rise of the main parameters' thresholds, responsible for the instability onset.
