Gotsulenko V. Increase of stability of work of systems of a forcing of liquids or gases at transformation of heat and other forms of energy to a pressure of a stream

The dissertation is devoted to revealing of the reasons of self-excitation of self-oscillations at vibrating burning, work impeller pumps caused cavitation, and also a supply of heat in streams of a liquid or gas, and action in system of a siphon. The developed ways of management can be used by amplitude of fluctuations for maintenance of steady work condensate pumps and at work of pumps in cavitation a mode before failure of submission, for maintenance stable works of compressors, for reduction of amplitude of fluctuations of vibrating burning. Own experimental researches of centrifugal pumps are put in a basis of the dissertation and mathematical modelling non-stationary modes caused is applied by change of a pressure at transformation into him of energy of a stream. The algorithm which is applied in researches is constructed on updating numerical methods and their adaptation for numerical integration of the equations with late argument, classical method Runge-Kutta and own method of the author alsois used.
