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 GNP. ...
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 ...
Graphene is a 2D single layer of carbon atoms, superior to graphite in mechanical properties and thermal conductivity. Polymer/graphene composites can be fabricated using several techniques, however this study analyzed a solid state in situ method for the creation of polyamide-6 (PA6)/graphene composites. Thermal conductivity was measured using a Thermal Constant Analyzer by transient plane source method. Thermal conductivity of PA6-graphene composites increased with the increase of ...
The purpose of this study was to improve the wettability of silicon carbide (SiC) nanowires, in order for them to be used as thermoconductive fluids. Multiple experiments were conducted by exposing the SiC nanowires to hydrofluoric acid, tetraethyl orthosillicate, polyvinylpyrolidone and sodium hydroxide. Various tests, including x-ray diffraction, Fourier transformation-infrared, x-ray photoelectron spectroscopy, thermogravimetric analysis, scanning electron microscopy and transmission electron microscopy, were performed on these various materials to identify ...
The thermal conductivities of paraffin-based composite phase change materials (PCMs) containing different types of graphene nanoparticles were determined using the transient plane source method. It was determined that the thermal conductivity was increased by the addition of the nanoparticles, and the enhancement was greater for composites containing larger, and stiffer nanoparticles....
