Abstract

In this work, we describe the results of a mathematical simulation of the electromagnetic and hydrodynamic processes that occur in a liquid-metal aluminum conductor while the passing of a kiloampere single-pulse current of microsecond duration through it. It is found that the compression of the liquid conductor by the magnetic pressure occurs upon exceeding a certain threshold value of the pulse current, which is governed by the metallostatic pressure. The fields and absolute values of the flow velocities in the conductor depending on the current pulse parameters are determined.
