Experimental techniques for thermal contact resistance measurements

Experimental Thermal and Fluid Science, 1993
ABSTRACT A number of different experimental techniques have been used to determine the thermal resistance of materials in contact, depending upon specific test requirements. These techniques and associated experimental facilities are reviewed, including the traditional cut-bar vertical-column test facilities, and more specialized facilities and ...

Thermal-Contact Resistance in Finned Tubing

Journal of Heat Transfer, 1960
Interference-fit finned tubes depend for their heat-transfer capability upon a contact pressure between fin and tube. The bond resistance under such conditions is relatively small compared to the other resistances in the heat-flow path. At elevated temperatures, however, differential thermal expansion between fins and tubes completely relaxes the ...

Thermal Contact Resistance: Experiment Versus Theory

International Journal of Thermophysics, 1998
With a knowledge of the thermal resistance value associated with an asperity, a model for the thermal contact resistance of a given interface is obtained by considering that each asperity of surfaces in contact is a flux tube. Calculation of any of the thermal conductances depends on the contact radius of each asperity. This radius increases with load,

Modeling Thermal Contact Resistance

1995
One difficulty in using cryocoolers is making good thermal contact between the cooler and the instrument being cooled. The connection is often made through a bolted joint. The temperature drop associated with this joint has been the subject of many experimental and theoretical studies. The low temperature behavior of dry joints has shown some anomalous

Instrumentation to measure thermal contact resistance

Measurement Science and Technology, 2003
Instrumentation was developed to measure the thermal contact resistance across metallic contacts by varying the contact pressure in different environments. Experiments were conducted on oxygen free, high conductivity (OFHC) copper cylindrical flat contacts and the measured thermal contact resistance is in good agreement with the theoretical models ...

Thermal Contact Resistance of Anisotropic Materials

Journal of Heat Transfer, 1970
This work presents an extension of the understanding of thermal contact resistance to include anisotropic materials. The extension involves a mathematical geometric transformation which leaves the thermal currents unchanged while making the temperature distribution in the anisotropic materials soluble by previously published methods. The development of

Thermal contact resistance in thermophysical measurements

Journal of Engineering Physics, 1982
The author describes the basis for an experimental correction to the thermal contact resistance (TCR) in investigation of thermal conductivity and thermal diffusivity of solids, using specimens in the form of plates. Relations are obtained for thermal deformation of specimens and the contact pressure to compensate for thermal deflection.
