Papchenko A. Hydrodynamics of the working process of a heat generating unit of multi-functional application

The thesis presents the results of investigation of the working process of a heat generating unit. The influence of parameters of flow passages (diameter, width, number of blades of the impeller, number and width of vanes of stator wheels), rotational speed and properties of the working medium on the performance curves of the unit was determined. An approach for composing the energy balance of the heat generating unit was suggested, when using it as a multi-functional equipment. The essence of the thesis is determination of an analytical dependence of the power of the unit on a number of parameters, and its correction by using a power coefficient obtained by computation using the software package FlowVision. Then the obtained results were checked by comparison with the results obtained in the experimental part of this research.
