Influence of pH on Nanofluids’ Viscosity and Thermal Conductivity

The authors used the transient plane source (TPS) technique to investigate the effect of pH on nanofluid thermal conductivity and viscosity. Cu and Al2O3 nanoparticles were dispersed in water to create two nanofluids. pH was then varied and thermal conductivity and viscosity measurements were made on the nanofluids. An optimal pH was found to give the lowest viscosity and highest thermal conductivity, and a significant improvement in thermal ...

Analysis of factors influencing thermal conductivity and viscosity in different kinds of surfactant solutions

Surfactants are often used in nanofluids to help improve dispersion and prevent aggregation of the resident nanoparticles. In this study, the researchers used the transient plane source (TPS) technique to measure the thermal conductivity of a variety of nanofluids with different surfactants of varying concentrations, at different temperatures and pH values. For surfactants, thermal conductivity stabilizes after the addition of a certain concentration of that surfactant. Strongly acidic and alkaline ...

Porous mullite ceramics with low thermal conductivity prepared by foaming and starch consolidation

Using industrial grade mullite powder and a foaming and starch consolidation process, a series of porous mullite ceramics were prepared. These ceramics were analyzed by a thermal constants analyzer, and it was determined that the ceramics had low thermal conductivities and would make good thermal insulators. The porosity of the synthesized ceramics can be controlled by the sintering temperature and by adjusting solid loading. The ceramics were subjected to theoretical ...

Magnetic alignment of Ni-coated single wall carbon nanotubes in heat transfer nanofluids

Ni-coated single-walled carbon nanotubes (SWNTs) were dispersed in four fluids (of varying viscosities) to create four different nanofluids. Due to the magnetic properties of the coated nanotubes the researchers induced a magnetic field to increase the thermal conductivity of the nanofluids. The increase in thermal conductivity was due to the alignment of the carbon nanotubes into chains due to the magnetic field. A Thermal Constants Analyzer was used to measure ...

Thermal and Rheological Properties of Microencapsulated Phase Change Materials

Microencapsulated phase change materials (MPCMs) are excellent materials for the storage of thermal energy, and through their dispersal into a carrier fluid, microencapsulated phase change slurries (MPCS) can be prepared. These slurries exhibit both excellent thermal energy storage and heat transfer properties. A series of MPCS were prepared for this research and subsequently tested for thermal conductivity and specific heat. Other methods of quantification include DSC, TGA, rheometry, and infrared ...
