In order to study the correlation between meso-structure and thermal conductivity of deep rocks at high geo-temperature, the thermal physical tests were carried out on the granite samples in the depth of 1500m to 2000m in Sanshandao, firstly, the polarizing microscope was used to test the micro characteristics, the nuclear magnetic resonance was used to test the distribution of pore structure, finally, the heat transfer characteristics of dry and wet rock in medium and high temperature environment are obtained by using transient plane source method, The influence of external environment and meso-structure of rocks on thermal conductivity was discussed. [1] In this study, the anisotropic thermal conductivities of two-dimensional (2D) plain woven and twill woven carbon-fiber/epoxy composites are measured at different temperature with the one-dimensional (1D) steady-state method, transient plane source (TPS) method and transient hot wire method, respectively. [2] The thermal conductivity of both PCMs and TPMS-PCM composite were measured using Transient Plane Source (TPS) method. [3] In the presented work, thermophysical properties of four limestones were investigated in dry and moist state under ambient conditions by using a transient plane source method. [4] This new transient thermal offset (TTO) method is derived from the widely used transient plane source (TPS) method but intentionally deviates from the condition to not apply thermal pulses that probe deeper than the boundaries of the thin sample. [5] In this article, we present the effective thermal conductivity of open-cell polyurethane (PU) foam (20 PPI) with ~10 μm thick nickel coating measured by transient plane source (TPS) method. [6] The estimated thermal properties are also validated against experimentally measured values obtained using the Modified Transient Plane Source (MTPS) sensor. [7] This work explores the feasibility of coupling two different techniques, the impedance and the transient plane source (TPS) principle, to quantify the moisture content and its compositional parameters simultaneously. [8] Thermal properties measured using the transient plane source method, complemented the ignition study. [9] 24 drilling cuttings samples from rocks down to a depth of 2000 m were selected for transient plane source thermal conductivity tests, and an effective thermal conductivity method was used to predict the thermal conductivity of rocks corresponding to each formation. [10] Based on the transient plane source method of thermal physics, the thermal properties of loess with different water content during the freezing process were tested. [11] The heat transport phenomenon of h-BN/epoxy and r-GO/epoxy nanocomposites were investigated using the transient plane source (HOT DISK) technique at room temperature. [12] The Hot Disk transient plane source (TPS) method allows characterizing the thermal properties of various materials in a few minutes. [13] The computational results are validated experimentally by applying the anisotropic transient plane source method. [14] Differential scanning calorimetry (DSC) and transient plane source (TPS) methods were used to measure, in small samples, the temperature dependency of melting/solidification heat, specific heat, and thermal conductivity of the NaNO3–ZnO microcapsules. [15] Transient Plane Source Method was introduced so as to calibrate thermal physical parameter(density, specific heat ratio and thermal conductivity) of model material with high accuracy. [16] Experimental analyses are performed to determine thermal conductivity, thermal diffusivity and volumetric specific heat with transient plane source method on hollow sphere structures. [17] A transient plane source technique was used to study these properties under ambient conditions. [18] Additionally, thermal conductivity measurements were performed in both Fe3O4@PAA and Al2O3 NFs at different NP concentrations, using the transient plane source technique. [19] Thermal conductivity and compressive strength of the samples were measured by a thermal conductivity analyzer with a modified transient plane source, and the mechanical test method, respectively. [20] Thermal transport properties of all samples were done by using advantageous transient plane source method. [21] Comparisons are made for the effective thermal conductivity of translucent materials determined by the hot strip method, one-dimensional steady state method, transient plane source method and Rosseland model. [22] Complementarity, thermal conductivity was measured in the rock samples before and after the application of a thermal treatment by means of C-Therm TCi device, a Modified Transient Plane Source (MTPS). [23] Experimental measurements of thermal conductivity and thermal diffusivity of wood were performed using the heat flow meter and transient plane source technique. [24] This article presents the thermal conductivity and thermal diffusivity measurements performed on ex-vivo bovine liver samples using the transient plane source method. [25] 1 wt% of graphene dispersed emulsifier cutting fluids are prepared using different surfactants and thermal conductivity is measured by modified transient plane source method using C-Therm thermal conductivity apparatus and results are compared with base fluid. [26] Using the transient plane source (TPS) method, in combination with a servo-controlled compression machine and an acoustic emission (AE) monitoring system, lateral thermal conductivities, stress–strain relations and AE responses of the thermally treated specimens during uniaxial compression were measured. [27] In this study, the thermal conductivity of two ceramic fiber insulations, Fiberfrax T-30LR laminate and 970-H paper, was measured as a function of atmospheric temperature and compression in an air environment using the transient plane source technique. [28] The outcomes of this study are threefold: regarding TES media, not all three TES technologies have been studied at the same extent; just few papers have been reported on thermochemical storage, being phase change materials and sensible the most studied; Regarding thermal conductivity techniques, transient plane source, laser flash apparatus and transient hot wire are the most used, whereas modulated DSC and 3ω the least; And lastly, regarding the measurement procedure, the data is widely spread especially for accuracy, sample size and repetitions within the same material/technique. [29] Such an autoclave facilitates a Transient Plane Source (TPS) sensor in order to perform thermal conductivity measurements of the high-temperature metal hydrides. [30] The values of effective thermal conductivity (λe),effective thermal diffusivity(χe) and volumetric heat capacity(QCp) have been determined using transient plane source (TPS) measurements. [31] The thermal conductivity of thermal interface materials (TIMs) has been studied using a transient plane source (TPS) method. [32] In this work, the thermal conductivities of methane hydrate and methane hydrate-bearing seasand were investigated by the transient plane source (TPS) technique. [33] The thermal properties of Jalore granitic rocks were determined using the transient plane source (TPS) technique in the temperature range from 25 °C to 250 °C. [34] A Transient Plane Source (TPS) method was used to measure the thermal conductivity and diffusivity of the proposed materials at different temperatures (40 °C, 60 °C, 80 °C, 100 °C, and 120 °C). [35] Samples were analysed by proximate, ultimate and thermogravimetric analyses, transient plane source, and a cone calorimeter. [36] The transient plane source (TPS) technique has recently garnered attention due to its ability to measure thermal properties of an extensive range of isotropic materials such as solids, liquids and powder. [37] This article presents a combined experimental and computational study of thermal conductivity in 5-harness-satin woven Nextel 440 fibers, using the hot-disk transient plane source method and computational thermo-mechanical modeling by finite-element analysis. [38] The thermal conductivity enhancement in the nanocomposites is observed in comparison to pure PANI nanofibers, which was studied in a wide temperature range 0–100 °C by Transient Plane Source method. [39] Thermophysical characterization of three paraffin waxes (RT27, RT21 and RT35HC) is carried out in this study using DSC, TGA and transient plane source technics. [40] The hot disk transient plane source (TPS) method is a widely used standard technique (ISO 22007-2) for the characterization of thermal properties of materials, especially the thermal conductivity, k. [41] The measurements of these thermal transport properties of rice straw bale sample are carried out using transient plane source technique. [42] The subject of the paper which is a continuation of part 1 are issues related to the implementation of the stepwise transient plane source method. [43] Room temperature thermal conductivity values of selected composition of Th-U alloys were experimentally measured employing Transient Plane Source (TPS) technique using slab sample geometry. [44] 192 W/ (m K) tested by the Hot Disk via transient plane source method certifies that the composite is very applicable for insulation. [45] Thermal conductivity was studied by a transient plane source method dependent on the magnetic volume fraction and external magnetic field. [46] The authors’ approach to stepwise transient plane source method for measuring specific heat, thermal diffusivity and thermal conductivity of chosen materials: foams, polymers and metals has been presented. [47] Moreover, the LFA results are compared to other commonly used methods - a Hot Disk Transient Plane Source (TPS) system and a guarded heat flow meter (GHF). [48] Thermal conductivity was measured as a function of temperature and compression in air, helium, and partial vacuum environments using the Transient Plane Source (TPS) technique. [49] The measurements were performed using the single-sided Transient Plane Source (TPS) method.
