Investigation of the Thermal Conductivity and the Viscosity of Carbon Black Heat Transfer Nanofluids

Seven distinct samples of nanofluids consisting of different concentrations of spherical graphitized carbon black in an ethylene glycol solution were analyzed to determine their thermal and rheological behavior. The thermal conductivity measurements were made at 20°C and 30°C with a transient hot wire instrument made by Thermtest called THW-L2 and specifically designed to measure the thermal conductivity of liquids. This study was ...

Measurement of Thermal Conductivity of Kerosene – Graphene Nanofluid

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 ...

When rocks get hot: thermal properties of reservoir rocks

When attempting to extract reservoir fluid from rock, the rock is often heated. When the reservoir fluid is hotter it is less viscous and easier to extract. Knowing the thermal conductivity of the rock in question is therefore incredibly important to preform these procedures. This paper reviews the thermal conductivities of reservoir rocks by analyzing data collected from performing the transient line ...

Recylced natural wastes in metakaolin based porous geopolymers for insulating applications

This article aims at assessing the impact of rice husk ash and volcanic ashes on the processing of porous inorganic polymers. The addition of volcanic ash or rice husk ash in porous Inorganic Polymer Composites (IPC) allows for the reduction of sodium silicate necessary, improving the Si/Al ratio. Thermal conductivity was measured using an instrument through the transient plane source method. With the addition of aluminum content and rounded ...

Thermal conductivity and rheology behavior of aqueous nanofluids containing alumina and carbon nanotubes

Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids. In this study, the thermal conductivity of aqueous alumina and multi-walled carbon nanotube (MWCNT) nanofluids was measured using the transient plane source (TPS) method with a thermal constants analyzer TPS. During each trial, 0.015 W of power were administered to each sample for two seconds. Results of the experiment showed ...
