Heat transfer enhancement of Al2O3-H2O nanofluids flowing through a micro heat sink with complex structure

Nanofluids are used in heat sink applications to improve the rate of heat dissipation and reduce temperature gradients in electronics. This study specifically examined the thermal properties of Al2O3-H2O nanofluids used in micro heat sinks. An instrument measured the thermal conductivity of the Al2O3-H2O nanofluids using the transient plane source (TPS) method. Results showed that, as expected, thermal conductivity increased with the concentration of ...

Comparison of thermal properties measured by different methods

In this paper, the thermal conductivity of rock samples was tested using three different methods: the transient plane source (TPS) method, the divided bar method, and calorimetric method. Two rock samples were tested under the TPS method with different procedures (i.e. heating and cooling times, sizes of samples). The results of the TPS method were slightly lower than the results of the divided bar method, but yielded an acceptable ...

Tannin-based monoliths from emulsion-templating

Porous monoliths, often referred to as polymerised High Internal Phase Emulsions (polyHIPEs), are materials made of polymers that have applications ranging from chemical engineering to biomedicine. In this paper, a TPS instrument measured the thermal conductivity of tannin-based monoliths with the transient plane source (TPS) technique. Results showed that as the porosity of the polyHIPEs increased, the thermal conductivity decreased linearly, a characteristic that could be used for applications in ...

Thermo-optical properties of partially unzipped multiwalled carbon nanotubes dispersed nanofluids for direct absorption solar thermal energy systems

Water is being used to absorb incident light for use in solar power applications. Adding nanoparticles to water improves the solar collection efficiency. In this paper, a Thermal Analyzer measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluids increased with temperature and nanoparticle concentration....

Different ethyl alcohol secondary fluids used for GSHP in Europe

Ethyl alcohol based secondary heat transfer fluids are typically used in ground source heat pumps (GSHPs) in Sweden because of their attractive thermophysical properties and low toxicity. Denaturing agents must be added to ethyl alcohol based secondary fluids, and in Europe, the most commonly used are: propyl alcohol, n-butyl alcohol, methyl ethyl ketone, and methyl isobutyl ketone. In Sweden, only propyl alcohol and n-butyl alcohol can be used because of ...
