Vlasenko O. Methods for determining the intensity of heat transfer in multiphase and multicomponent media

The dissertation is devoted to experimental research aimed at creation of a method of forecasting the intensity of heat exchange in multiphase and multicomponent environments with limited thermophysical information properties The development of biogas technologies creates a positive energy, environmental and social effects. One of the important and unsolved problems in biogas technologies is compliance with the temperature regime. In this work, to process the results of experimental studies it is recommended to involve methods of non-stationary heat exchange, methods of a regular thermal regime, which are designed only for solid bodies. The proposed method of non-stationary heat exchange is used for bodies that consist of a solid and a liquid part, in which regular thermal is realized regime. The essence of the method is to study heat exchange in a "limited volume" at free, forced convection and with the help of the theory of similarity transfer to thermal stabilization processes in biogas plants. Methods of a regular thermal regime allow studying substances with limited information on thermophysical properties.
