Abstract
The conducted research is designed to develop scientifically sound recommendations in order to optimize design and layout solutions that ensure increased energy efficiency and operability of energy-producing installations for various purposes. The mechanisms leading to the formation of stable vortex structures in internal turbulent swirl flows occurring in complex channels of power plants are considered. The effects associated with the manifestation of the swirl flow crisis are considered. It is shown that the generation of stable vortex formations in the equipment elements of power installations can be directly related to the mechanism of excitation of dangerous vibro-resonance effects. A method for intensifying heat transfer in steam generating channels is proposed. The question of choosing the criterion of thermohydraulic efficiency for solving optimization problems is considered.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
