The subject matter in the article processes in control systems using vortical energy separators. The goal is an analysis of a vortical energy separator where the Ranque-Hilsch effect is considered. The tasks to be solved are consideration of the discovery history, the essence and using of the Ranque-Hilsch effect; main structures of vortical energy separators review; the possibilities of vortical energy separator consideration and its control features; highlighting relevant research areas. The following results were obtained. The paper considers the device of the vortical energy separator in which the Ranque-Hilsch effect is manifested. A number of basic parameters are described that determine the operating efficiency of the vortical energy separator and calculations are made to increase its efficiency. The results of the research are presented that related to the influence of the overall dimensions of the vortical energy separator, form, size and number of the inlet nozzles on its effectiveness. The main types of vertical energy separator design are described: counter-flow and uni-flow. The most popular option for obtaining a descriptive model of a vortical energy separator is to use the equations of thermal and hydrodynamics. However, for further control of systems based on the use of the Ranque-Hilsch effect, this approach is not practical. For this, other methods are used to determine the mathematical model of a vortical energy separator, related to the processing of its experimental frequency characteristics. In order to obtain accurate and adequate results of the correction system with the vortical energy separator, the method of interval logarithmic amplitude-frequency characteristics is used and its mathematical model has fractional exponents. The relevant research directions of the vortical energy separators and the variants of their practical use in the world are presented: engine building, medicine, acoustic systems, industry, thermoregulation systems, aviation. Conclusions. The scientific significance of the review is as follows: the definition of relevant areas in various kinds of scientific research.
