This paper aimed to develop a 3D simulation based on the TPS technique that analyzed the spiral geometry and properties of the sample material and TPS sensor. A numerical study was simulated to reproduce the transient curve generated by the experimental study. Results of the experiment showed that the temperature of the central rings in the sensor were higher than the peripheral rings. The numerical and experimental results were compared ...
Nano-inclusions are thermally conductive particles that improve the thermal conductivity of liquid mediums. In this paper, the thermal properties of Mg2Si were evaluated after the addition of TiO2 nanoparticles. An instrument measured the thermal conductivity of the nanofluid using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluid was the highest at lower temperatures, and did not improve with the addition of the ...
Phase change materials (PCMs) can be used as heat sinks to manage high temperature fluctuations in electronics. In this paper, a heat sink was generated from a paraffin/expanded graphite composite PCM, and the thermal conductivities of the materials were measured using the transient plane source (TPS) method of the Thermal Analyzer. Results showed that the composite PCM had a significantly higher thermal conductivity than the pure paraffin....
Phase change materials (PCMs) store large amounts of latent heat over small temperature ranges, so their application in the thermal regulation of buildings is becoming more popular. However, PCMs have low thermal conductivities, so micro-encapsulated PCMs (micro-PCMs) are being incorporated into PCMs to enhance their performance and improve thermal conductivity. In this study, micro-PCMs were mixed with thermally conductive, inorganic gypsum powder and glass fiber to produce gypsum boards. The ...
Carbon nanotubes (CNTs) combined with inorganic matrices are not structurally sound unlike singular CNTs which have good mechanical performances. Borosilicate glass, commercially known as Pyrex, is durable but has yet to be successfully fabricated using the sol-gel technique. In this paper, the sol-gel technique was used to manufacture borosilicate glass matrix composites with multi-walled carbon nanotubes (MWCNTs). The technique measured thermal conductivity of the materials using the transient plane source (...
