Measuring the coefficient of the thermal conductivity of aluminium with a laser

Optics Communications, 1987
Abstract Heating an Al bar with a Co 2 laser, using the ferroelectric crystal SBN as a probe to detect the temperature, we can obtain the coefficient of thermal conductivity of Al. The percentage error is less than 0.6%.

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

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.

Estimating the thermal-conductivity coefficients of multiphase materials

Journal of Applied Mechanics and Technical Physics, 1968
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.

Calculations of the Coefficient of Thermal Conductivity for Dissociating Hydrogen

The Journal of Chemical Physics, 1962
The kinetic theory of dilute monatomic gases and gas mixtures as applied to reacting polyatomic gases has been used to calculate the coefficient of thermal conductivity of dissociating hydrogen for temperatures from 1500° to 5000°K and pressures of 0.1, 0.5, 1, 2, 10, 50, and 100 atm.

Heat Capacity, Conductivity, and the Thermal Coefficient of Expansion

2018
Heat capacity depends on the initial and final states, and on the path of the transition between them. The heat capacity of the powder is approximately that of natural diamond in the 500-700K temperature range. The peculiarities of diamond film structure make it worthwhile to separate them into two conventional classes: the thin films and the thick ...
