The study of caloric properties, viscosity, density and heat of phase transitions will also provide information on the structural specificities of nanoMPTs in combination with CPMs, even at the level of "fine" sorption effects of the molecules of base fluids and surfactants on the surface of nanoparticles, which is impossible to investigate in a wide range of temperatures by other methods. Tests of the thermal storage devices using the developed nanoMPTs will be focused on studying the dynamics of changes in temperature fields in thermal storage devices under operational conditions; correlations of the main characteristics of thermal storage devices with operational parameters and efficiency parameters of SPP Product Description popup.authors Ivchenko Dmytro O Hlek Yana O Paskal Oleksiy A Semenyuk Yury V Khalak Viacheslav F Khlieva Olga Ya popup.nrat_date 2020-12-14 Close
