FIELD: physics.
SUBSTANCE: solid core in form of a rotation body with an electroconductive probe and a comparison electrode on the surface is immersed in a reservoir with electrolyte solution which simulates the lower mantle of the planet. Constant potential difference is applied to the probe and comparison electrode. The reservoir is brought into steady rotation. The solid core is displaced from the axis of rotation of the reservoir. The solid core is subjected to angular vibration and fluctuation of electric current in the circuit of the probe occurring with the frequency of the angular vibration is recorded. The average angular position of the probe over the period of vibration is changed by rotating the solid core. The velocity amplitude of angular vibration of the solid core is set greater than or equal to the difference between average angular velocities of the reservoir and the solid core. Angular vibration is achieved during rotation by moving a belt into a groove with spikes. Application of angular vibration to a stationary solid core is also possible.
EFFECT: enabling demonstration of flow separation from a discretely rotating solid core with reproduction of relatively low shift of the solid core from the axis of daily rotation, which is typical for a planet.
