C 73 Comparison of thermophysical properties for oil/refrigerant mixtures by use of the pulse heating method / P. V. Skripov, A. A. Starostin, D. V. Volosnikov, V. P. Zhelezny // International Journal of refrigeration. - 2003. - Vol.26, №6. - С. 721-728 Рубрики: ФИЗИКА Кл.слова (ненормированные): REFRIGERANT -- LUBRICANT -- MIXTURES Аннотация: The method of pulse heating for the study of thermophysical properties for oil/refrigerant solutions in a wide temperature range and for monitoring of an actual state of these systems has been developed. The regimes of linear heating and thermostabilization of the superheated probe are applied for solving our task. The objects of study are as follows: synthetic oils Mobil EAL Arctic 22, PLANETELF ACD22, XMPA, and solutions of carbon dioxide in these oils. The upper boundary, with respect to temperature, of the two-phase equilibrium region including the vicinity of the liquid–vapour critical curve of these systems, gas solubility in oils at various temperatures, short-time thermostability, and thermal conductivity of oils are considered. Inclusion of the thermally unstable states of a substance in investigation allows one to essentially extend the set of compared data |
A 10 A method of controlled pulse heating: Applications / P. V. Skripov, A. A. Smotritskiy, A. A. Starostin, A. V. Shishkin // Journal of Engineering Thermophysics. - 2007. - Vol.16, №3. - С. 155-163 Рубрики: ФИЗИКА Кл.слова (ненормированные): THERMOPHYSICAL PROPERTIES -- THERMAL STABILIZATION -- HIGH-MOLECULAR FLUIDS Аннотация: This paper is devoted to the state-of-the-art and technical potentials of the pulse heating method for the thin wire probe created in the Ural thermophysical school for studying the kinetics of spontaneous boiling and the related phenomenon of liquid attainable superheating. Special attention is paid to the search for technical means for controlling the power of the probe heating in a pulse experiment with the thermophysical properties of the substance taken into account. Applications of three particular cases are considered: techniques for the constant heating power, the thermal stabilization of the pulse-heated probe, and cooling of the shock-heated probe for investigating the behavior of multicomponent and high-molecular fluids essentially superheated above the temperature of phase equilibrium and/or temperature of molecule thermodestruction in a quasi-static process. Opportunities for application of the method are presented, in particular, for fast detection of volatile admixtures (including their traces) in high-molecular fluids, e.g., in oils of power equipment |

The experimental data were obtained in the temperature range from (273 to 355) K by a mixing method realized in an ice calorimeter. The behavior of the temperature and weight fraction dependencies of the enthalpy for the refrigerant-oil solution (ROS) of R600a and mineral compressor oil WF 15A have been examined \\\\expert2\\NBO\\Journal of Chemical and Engineering Data\\2010, v.55, p.1322.pdf |
