- There has been an increasing attention on single-tank thermal energy storage, attracted by the low cost, high efficiency and compactness in the operation.
- The application of thermal microscopes to the measurement of local thermal properties has drawn considerable scientific interest.
- Thermal properties of agricultural products are important to understand their thermal behaviour.
- The limited thermal energy transportation capability of conventional fluids curbs the energy-harvesting potential of renewable energy-harvesting systems.
- Among the various thermal properties, thermal conductivity of soils is one of the most important parameters to design a horizontal ground heat exchanger for ground-coupled heat pump systems.
- Ordered mesoporous oxide films have lower thermal conductivities than their corresponding dense films.
- Heat transfer in flow across a bank of tubes is of a particular importance in the design of heat exchangers.
- La2Zr2O7 used as a top coat material has low thermal conductivity and high stability at high temperature, but it also has a low fracture toughness, which limits its application.
- In evaluating the thermal properties of some porous media, such as aerogels, difficulties arise due to the following: (1) The media are transparent in some spectral intervals and opaque over other intervals and cannot therefore be treated as optically thin or as optically thick; (2) the conductive and the radiative heat transfer are coupled.
- There are three main types of solids whose thermal conductivity is important in the design of cryogenic apparatus: pure metals, alloys and disordered dielectrics.
- Over the past several decades, research on anomalous thermal expansion materials has been rapidly growing, and increasing numbers of compounds exhibiting negative thermal expansion (NTE) have been reported.
- Photovoltaic-thermal collectors (or PV-T collector) are hybrid collectors where PV modules are integrated as an absorber of a thermal collector in order to convert solar energy into electricity and usable heat at the same time.
- The reduction of package and chip size by the need of cost reduction on one hand and the need of high voltage metallization on chip for power applications on the other hand the thermal electrical-mechanical management concerning the reliability becomes more and more critical.
