Abstract

In the research work, conduction velocity sensors were successfully used to study the characteristics of turbulent flows arising in a liquid metal under the action of a rotating magnetic field in a vertical cylinder. At a certain magnitude of electromagnetic influence, on the graphs showing spectral energy of velocity pulsations there is observed a slope of ‘-5/3’, indicating developed homogeneous isotropic turbulence and spreading in a frequency range of up to two decades. The level of velocity pulsations varies from 4 to 10 % of the azimuthal rotation velocity. It is shown that the identified peaks in the velocity pulsation spectra correspond to the frequency of the liquid metal rotation around the cylinder axis. A nonlinear graph of the dependence of the liquid metal rotation frequency on the current frequency in the coils with a maximum near 50-75 Hz was obtained.
