Eroshenko, Registration Date 10-01-2012 Organization The National Technical University of Ukraine, the Department of Heat Engineering and Energy Saving, the TME Laboratory. popup.description2 The object of investigation is heterogeneous lyophobic systems with extremely developed interfacial surface of the "liquid - capillary-porous matrix" - repulsive clatrate (RC) as the working substance on the basis of various porous matrices and fluids. The subject of investigation - 1) disclosure of physical and thermodynamic hysteresis effect at the PV-diagrams, 2) the nature of the repulsive forces at the interface "liquid - solid," study the possibility of controlling them. The synthesis of ideas about the nature of the hysteresis in the RC given theoretical and experimental research: comparing the experimental and theoretical understanding of hysteresis for the processes of compression and expansion of the RC is obtained. The recommendations for choosing the components of the RC, depending on their functional purpose - accumulation, dissipation, or energy conversion are developed. Thermodynamic parameters for the RC with different levels of hysteresis are obtained. The theoretical studies of physical and electro-chemical principles of controlling configurative repulsive clatrates (CRC) on the molecular level, the analytical expressions for the thermodynamic functions of the CRC are produced. The recommendations for synthesis of CRC with desired properties and characteristics are designed.
