Kerosene graphene nanoplatelets (GNP) nanofluids have a potential use in regenerative cooling of semi-cryogenic rocket thrust chamber. Before they can be used, more must be known about this substance's physical qualities. This study focuses on finding the effective thermal conductivity of this type of nanofluid, specifically at .005, 0.05 and 0.2 weight percentage (wt%) and 300, 500 and 750 mm2/g, specific surface area (SSA) of ...
This article studied the thermal conductivity values and measurements for the following two systems using the transient hot wire (THW) and transient plane source (TPS) techniques: ethylene glycol with added CuO, TiO2, or Al2O3 nanoparticles and water with added TiO2 or Al2O3 nanoparticles or multiwall carbon nanotubes (MWCNTs). A TPS technique using a thermal conductivity analyzer ...
This article studied the thermal conductivity of deionized (DI) water and ethylene glycol (EG) based nanofluids with varying temperatures for different volume fractions of N-(rGO-MWNTs) (nitrogen doped hybrid structure of reduced graphene oxide (rGO) and multiwalled carbon nanotubes (MWNTs)). The thermal conductivity was found by using the transient plane source (TPS) method by using a Thermal Analyser. From the experimental results, it was noted that the thermal conductivity of ...
An oscillating heat pipe (OHP) is a pipe that transports heat from the evaporator to the condenser via a complex pulsating action. Nanofluids and self-wetting fluids can be used to improve the heat transport capabilities of the OHPs. This study looks at heat transport performances of OHP with different binary fluids. Thermal conductivity was measured using a thermal analyzer, with transient plane source method. Nanofluids were found to have a ...
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 nanofluids using the transient plane source (TPS) method. The thermal conductivity of Al2O3/water nanofluids was further enhanced with the addition of MWCNTs because ...
