Thermal contact resistance at low contact pressure: Effect of elastic deformation

Measurement of through-plane effective thermal conductivity and contact resistance in PEM fuel cell diffusion media

“…27 [19] demonstrated an experimental methodology to determine the thermal conductivity of deformable diffusion materials as a function of compaction pressure. The thermal conductivity and the thermal contact resistance to an aluminium plate for an uncoated SolviCore GDL were determined at various compaction pressures.…”

“…(4), although the thermal resistance of the sample is a function of its effective thermal conductivity, k m , and thickness, the sample-to-metal contact resistance is a complex function of thermal conductivities, contact pressure and surface characteristics such as surface roughness, asperity, and the sample microhardness [27]:…”

The Parameters Affecting on Thermal Contact Conductance-a Review

“…A reduction of the interface temperature resulted in a smaller value of thermal contact conductance. Majid Bahrami, M. Michael Yovanovich, J. Richard Culham (2005) [2] This study is carried out at low pressure. The effect of elastic deformations was determined beneath the plastically deformed microcontacts is determined by superimposing normal deformations due to self and neighboring contact spots in an elastic half-space.…”

In-situ Observations of a Multi-Asperity Real Contact Area on a Submicron Scale

“…In the literature [22] to [31] several experimental techniques are described for real-contact-area measurements. Probably the most practical in-situ methods for real-contact-area measurements are based on the electrical [24] and thermal [25] contact resistance, as well as ultrasonic [26] and [27] and optical [28] and [29] principles. However, the most common technique for a realcontact-area measurement is the optical method, the only critical limitation of which is the transparency of one of the contacting bodies so the light can pass through into the contact.…”
