In this study, multi-walled carbon nanotubes (MWCNTs) were added to Al2O3/water nanofluids to determine their heat transfer and temperature drop properties compared to water and Al2O3/water nanofluids. A TPS thermal constants analyzer measured the thermal conductivity of the Al2O3/water ...
Borehole heat exchangers are used in conjunction with ground source heat pumps in Nordic countries. Aqueous ethanol solutions are commonly used with other secondary fluids such as water in borehole heat exchangers to decrease the freezing point of the liquid. However, ethanol based mediums contain ...
