“…Referring to the previous argument in the introduction part, TCC (or TCR) has been involved in many fields such as aircraft, semiconductors and electronic device [19]. As mentioned above, TCC could be estimated by several simplified models, but it is still challenging to estimate the correct value owing to the uncertainty of several parameters.…”

The effect of Thermal Contact Conductance (TCC)onthermal conductivity of mortar has been studied at the interface between the limestone and cement paste. A novel methodology, which involves the use of Scanning Electron Microscope (SEM) to scan the image of the interface in mortar, the software PlotDigitizer to create a set of points of the interface, and the FE software Abaqus/CAE to perform heat transfer simulation, is proposed in this study. Moreover, several hypotheses at the interface such as the gaps, flaws, and Interfacial Transition Zone (ITZ) are also highlighted. Temperature drop, thermal conductivity, and the TCC coefficient has been calculated for each model in order to understand the effect of TCC on cement-based materials thermal properties. The results show that the temperature drops at the interface are very low and the TCC coefficients are very high so that it can be ignored in heat transfer simulation except for a large air gap at the interface. Thus, it can be concluded that the TCC has no influence on the thermal conductivity of mortar.

“…Its initial temperature is T M0 , see again figure 1. Quite obviously, and as discussed elsewhere [20], the hypothesis of ideal thermal contact is only partly satisfied: one should rather consider the actual roughness of the bodies (of both the skin surface and the external material) as well as even more complicated details which, on average, give rise to a contact thermal resistance which is quite difficult to be properly and quantitatively taken into account [21]. In view of our needs of a simple rendition of this problem, we insist with the perfect contact hypothesis throughout the following discussion.…”

In this work we address the well-known fact that upon touching different materials, even if at the same environment temperature, one perceives warmer or cooler sensations depending on properties other than temperature itself. A simple, one-dimensional, non-stationary model for thermal behavior of the human skin layer is devised mainly with educational purposes and the associated Fourier heat equation is solved and discussed. In particular, we emphasize the fact that thermal conductivity alone is not adequate to properly characterize different thermal sensations and the so-called effusivity is instead needed to support a quantitative description. We also obtain some information, within the framework of this model, about the specific response of the skin thermal receptors. We furthermore suggest a possible, direct experimental estimate of thermal effusivity based on the use of infrared imaging in a demonstrative and educational perspective.

“…The target thermal conductivity varies, depending on the industry and intended application, with some aiming at ~10 Wm −1 K −1 while others target more than 25 Wm −1 K −1 [212]. There is also a specific goal of reducing the thermal contact resistance [213], [214]. These industry needs and market trends open a wide application domain for graphene and FLG as fillers in thermal composites.…”

We provide a summary of the fundamentals of thermal management, outline the stateof-the-art in the field of thermal interface materials, and describe recent developments in graphenebased non-curing and curing composites used for thermal management. The discovery of unique heat conduction properties of graphene and few-layer graphene motivated research activities worldwide focused on creating efficient graphene-based thermal interface materials. While the initial focus of these studies was on obtaining the maximum possible thermal conductivity of the composites, recently the attention has shifted to practical problems of minimizing the thermal contact resistance at interfaces, optimizing the size distribution of graphene as filler, and addressing the issues of scalability, stability, and production costs at commercial scales. We conclude the review with a general outlook for commercial applications of graphene in the thermal management of electronics.
