METHOD OF ELIMINATING TURBULENCE IN ROTATION FLOW Russian patent published in 2019 - IPC F15D1/06 

FIELD: technological processes.

SUBSTANCE: invention relates to methods for reducing intensity of turbulence in flows with rotation up to its complete elimination and can be used in the processing of liquid metals and melts, for example, by centrifugal casting of metals and alloys, as well as by growing single crystals from liquid melts and solutions. To eliminate turbulence in the currents between two rotating coaxially arranged rotation bodies, a mechanical action is applied to the external rotation body, providing modulation of the angular velocity of rotation of the body in time along a sinusoidal dependence with respect to the mean nonzero value with the fulfillment of the ratio f_m<0.1f_r, where f_m – modulation frequency, f_r – the average frequency of rotation of the body.

EFFECT: achieved when using the proposed technical solution is the complete elimination of the turbulence of the flow and transfer it to the laminar flow mode.
