Kerosene is used as a coolant in engines, however like many conventional heat transfer fluids, it has a low thermal conductivity. Nanofluids are suspensions of thermally conductive nanometer sized particles in a base fluid. This paper explores the thermal properties of a Kerosene based nanofluid with copper oxide (CuO) nanoparticles. The thermal conductivity meter measured the thermal conductivity of copper oxide/Kerosene nanofluids using the transient plane source (TPS) technique. ...
Soft tooling processes use flexible polymeric materials to manufacture moulds. However, the malleable materials used for soft tooling, such as silicone rubber, have low thermal conductivities and take an extensive amount of time to cool. In this study, metallic (Aluminum fine powder, grey iron, copper, magnesium, titanium, zinc) and non-metallic (graphite, silicone, glass) thermally conductive filler particles were added to silicone rubber to condense the cooling time of soft tooling ...
Weeds are invasive species that have yet to be controlled and cost nations millions of dollars per year in crop losses. In this experiment, two of the worst weeds in the world, Lantana camara and Parthenium Hysterophorus, were studied to determine their capability of producing heat transfer fluids (“biofluids”) that can be sold to reduce the economic burden they cause. The Thermal Constants Analyzer measured the thermal conductivity of the ...
Efficient thermal insulation is becoming increasingly important as people spend more time in buildings. Aerogel blankets are highly porous materials made of polymeric fibers coated with aerogel particles that are used for building insulation. This paper aimed to explore the effect of moisture on the thermal properties of insulating aerogel blankets, because in humid environments, condensation within building insulation heightens thermal conductivity. The thermal constants analyzer TPS measured the thermal ...
This paper examined the properties that affected the thermal conductivity of Aluminum Oxide (Al2O3) nanofluids with a base fluid of propylene glycol. Samples were prepared with volumetric percentages of 0.2%, 2%, and 3% Al2O3, and 22 replicates were completed over time. A Thermtest Transient Plane Source TPS measured the thermal conductivity of the nanofluids. Results showed that the 3% Al2O3/propylene glycol solution had the highest thermal conductivity....
