STUDY OF THE EFFECTIVENESS OF CHANNEL CONTROL STRATEGIES IN THE PROBLEM OF STABILIZATION OF A TURBULENT HYDRODYNAMIC FLOW

Abstract

The article considers the problem of stabilizing the value of the turbulent flow parameters described by the stochastic chaos model. As a basic control option, versions of channel strategies based on overrunning of current observations of the stabilized parameter from the range of acceptable values (channel) are considered. On the basis of numerical experiments, the potential possibilities of channel control strategies are investigated. It is shown that the main problem for achieving flow stability is the extremely high level of the variability of the system component of observation series, which is the realization of stochastic chaos. Versions of improved channel control strategies are given, the main directions for increasing the efficiency of functioning of channel stabilization technologies for turbulent flows are indicated
