“…In practice, the accurate value of TCR is difficult to obtain through only theoretical analysis, and experimental methods are widely used to measure TCR [11][12][13][14]. According to the definition of TCR, the steady-state method was developed for TCR measurement by determining the temperatures on the contact interface and applied heat flux [15][16][17]. For transient methods, TCR is known by measuring the changes in correlated parameters under an applied thermal disturbance [18][19][20].…”

A novel method involving the effect of thermal contact resistance (TCR) was proposed using a plane heat source smaller than the measured samples for improving measurement accuracy of the simultaneous determination of in-plane and cross-plane thermal conductivities and the volumetric heat capacity of anisotropic materials. The heat transfer during the measurement process was mathematically modeled in a 3D Cartesian coordinate system. The temperature distribution inside the sample was analytically derived by applying Laplace transform and the variables separation method. A multiparameter estimation algorithm was developed on the basis of the sensitivity analysis of the parameters to simultaneously estimate the measured parameters. The correctness of the algorithm was verified by performing simulation experiments. The thermophysical parameters of insulating materials were experimentally measured using the proposed method at different temperatures and pressures. Fiber glass and ceramic insulation materials were tested at room temperature. The measured results showed that the relative error was 1.6% less than the standard value and proved the accuracy of the proposed method. The TCRs measured at different pressures were compared with those obtained using the steady-state method, and the maximum deviation was 8.5%. The thermal conductivity obtained with the contact thermal resistance was smaller than that without the thermal resistance. The measurement results for the anisotropic silica aerogels at different temperatures and pressures revealed that the thermal conductivity and thermal contact conductance increased as temperature and pressure increased.

“…1. Schematic for mechanism of thermal contact resistance A large number of experiments have been implemented via diverse characterization methods to study the interfacial heat transfer that the interfacial separation is from atomic level to engineering application level (~μm) [2]. The researchers have investigated many factors with regard to the TCR, which includes the materials, the surface roughness and waviness, the interface temperature, the direction of the heat flux, the contact pressure, load cycle and the contact regions under different resolution [8][9][10][11].…”

Thermal contact has always been a hot issue in many engineering fields and thermal contact resistance (TCR) is one of the important indicators weighing the heat transfer efficiency among the interfaces. In this paper, the contact heat transfer of conforming rough surfaces is theoretically re-estimated considering both the heat transfer from contact and non-contact regions. The fluctuational electrodynamics (an ab initio calculation) is adopted to calculate the thermal radiation. The contribution of contact regions is estimated by the CMY TCR model and further studied by modelling specific surfaces with corresponding surface roughness power spectrum (PSD). Several tests are presented where aluminum and amorphous alumina are mainly used in the simulations. Studies showed that there exists a significant synergy between the thermal conduction and near-field thermal radiation at the interface in a certain range of effective roughness. When the effective roughness is near to the scales of submicron, the nearfield radiation effect should not be neglected even at room temperature.

“…Reduction of TCR is the issue for discharging heat waste efficiently. In terms of TCR measurement, the steady state method [1] is generally used to measure the overall TCR of the bulk sample, additionally as unsteady methods, the thermo reflectance [2] method and the 3 ω method [3] are studied to measure TCR of the homogenous thin film sample. However, the method to measure the local TCR in the contact interface is not established.…”

This paper proposes a new thermal contact resistance measurement method using lock-in thermography. By the lock-in thermography with an infrared microscope, the temperature distribution across the contact interface was visualized in the sample side surface. Meanwhile, a new thermal contact resistance measurement principle was derived by the superimposition of the temperature wave from virtual heat sources in consideration of the thermal contact resistance at the interface. Consequently, the thermal contact resistance was obtained as a fitting parameter by fitting the theoretical curve to the experimental amplitude and phase lag. the validity of the principle was shown.
