Gotsulenko V. The analysis and prevention of instability of streams of the heat carrier in elements of the heat power equipment.

Object of research - combustion chamber of industrial units, dynamic self-oscillation dampers, the air supply system comprising a blade blowers. The aim is to determine the causes and mechanisms of thermal-hydraulic instabilities of flow of the coolant, in particular a longitudinal thermoacoustic oscillations, and based on this - the development of methods for control of the amplitude of these fluctuations to prevent their destructive effects on the elements of heat power equipment. Research methods - methods of mathematical physics, theory of stability and bifurcations of a dynamical system. Theoretical and practical effects - the developed method of calculation of parameters of self-oscillations in the elements of heat-power equipment may be used in the design of combustion chambers and vibration combustion devices useful purpose. Novelty - the method of calculating the frequencies and amplitude of self-oscillations of flow of the coolant in the elements of heat power equipment. Built a theoretical model of damping self-oscillation data. Degree of implementation - the obtained results are used at PJSC "Xarcyzskij trubnyj zavod", OJSC "Pridneprovskij mexanicheskij zavod" and OJSC "Rotis Plus". Area of application - engineering thermal physics.
