Thermal-conductivity coefficients of six liquid aromatic hydrocarbons

Journal of Engineering Physics, 1978
Using experimental λ andρ data, equations are developed for six aromatic hydrocarbons which describe λ within the limits of experimental accuracy over the temperature range 298–573°K at pressures up to 500 bar.

Estimating the thermal-conductivity coefficients of multiphase materials

Journal of Applied Mechanics and Technical Physics, 1972
A mixture consisting of n homogeneous phases having certain properties is considered. The geometry of the phase domains is arbitrary and the mixture as a whole is considered to be statistically homogeneous but generally anisotropic. Ideal conditions of thermal contact (a continuous temperature and thermal flux) at the phase boundary are assumed.

A Study of Poor Conductor’s Thermal Conductivity Coefficient Measurement

Applied Mechanics and Materials, 2013
When measuring the thermal conductivities of poor conductor with steady-state method, some errors should be introduced through the process of the experimental principle derivation to the experimental data measurement. To satisfy the need of measurement, this study aims to improve the structure of the “TC-I1 Type thermal conductivity measuring apparatus”

Determination of the thermal conductivity coefficient of inhomogeneous media

AIP Conference Proceedings, 2014
This paper proposes an approach to the determination of the thermal conductivity coefficient of the inhomogeneous multiphase material when thermal properties of the individual phases are known. This approach is very similar to the method of determining the effective stress-strain properties. Problems in determining the effective thermal characteristics

Transport in two dimensions. II the thermal conductivity coefficient

Physica A: Statistical Mechanics and its Applications, 1978
Abstract The study of generalized transport coefficients in two dimensions is continued. In this article, the thermal conductivity coefficient is examined. The Mori formalism is used and the set of variables consists of all finite multilinear products of two collective conserved variables, the energy density and the momentum density.

Heat transfer coefficients and thermal conductivity of cold liquids

International Journal of Heat and Mass Transfer, 1969
Abstract A method for measuring the thermal conductivity of a low temperature liquid and the heat-transfer coefficient between a freezing ice sphere and the low temperature liquid is presented. The calculations are based on equating the quantity of heat liberated by a freezing ice sphere to the amount of heat that crosses the ice-“mold” interface. By

New Method of Measurement of Coefficient of Thermal Conductivity

Applied Mechanics and Materials, 2014
Several conventional steady-state measuring methods of material coefficient of thermal conductivity was systemically compared and discussed. The limitations and shortcomings of the infinite flat layer method, the infinitely long cylinder method and the concentric spherical shell layer method were pointed out.
