Thermal Conductivity and Thermal Diffusivity of Liquid Aromatic Hydrocarbons Undistorted by Radiation Heat Transfer

The values of thermal conductivity and thermal diffusivity are measured for seven substances (benzene, toluene, -n-m-xylenes, ethylbenzene, and isopropylbenzene) at temperatures T = 293–593 K and pressures P = P _S – 30 MPa. The obtained values of thermal conductivity and thermal diffusivity differ from the reference values by not more than 15%. The generalizing dependences are given, which describe the thermal conductivity, thermal diffusivity, and heat capacity per unit volume of n-alkanes, alkenes, and aromatic hydrocarbons.     

An Investigation of the Thermophysical Properties of a Liquid in a Flow Using the Method of Pulse Heating

The theoretical principles are described of measuring the thermophysical properties of a liquid in a flow during a short pulse of heating a quick-response probe. A plane probe and a linear probe are used to measure the thermal activity, thermal conductivity, thermal diffusivity, and kinematic viscosity of some liquids at different velocities of flow.     

Thermal conductivities of liquid n-alkanes and 1-alkenes corrected for radiative energy transport. part 2. Data fitting for a wide state-parameter range

An equation is proposed to describe the molecular thermal conductivities of liquid n-alkanes and 1-alkenes over wide ranges in the state parameters, which is based on the law of corresponding states. Measurements on the whole deviate from the equation by not more than 2–3%. The measurements on n-alkanes and 1alkenes have been used in the fitting.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 59, No. 5, pp. 827–831, November 1990.     

Thermal conductivity of n-alkanes and 1-alkenes. Undistorted by radiant energy transport. I. Results of experimental study

Results are presented from an experimental study of molecular thermal conductivity of liquid n-alkanes and 1-alkenes using the hot wire method. Measurements were performed at pressures up to 50 MPa and at temperatures from 300 to 640 K. The new experimental data appear to be low by 10% or more when compared to accepted values.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 59, No. 4, pp. 662–667, October, 1990.     

Application of pulse heating method for various thermal studies

An experimental device is described, which uses the pulse heating method for a low-inertia transducer with an automatic system of information gathering and processing. The possibility of measuring the thermal conductivity of the liquid, gaseous, and solid materials by linear and planar transducers is shown. The thermal conductivity of n-tetracosane at the phase transition is measured. A method of measuring the thickness of layers is proposed.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 63, No. 4, pp. 436–441, October, 1992.     

Water Solubility of Carbon Dioxide under Supercritical and Subcritical Conditions

The solubility of carbon dioxide in water at t = 25, 50, 100, and 150°C and p = 10–80 MPa is studied experimentally by a static method in a constant-volume cell. The results are described by the entropy method of similarity theory. The calculated and experimental data are in satisfactory agreement.
