Controlling the temperature of electronics under harsh conditions is important for vehicular, aerospace, and other industrial applications. Phase change materials (PCMs), such as paraffin, use latent thermal energy storage (LTES) to store large amounts of latent heat over small temperature ranges, and are being investigated for use in industrial sectors. However, PCMs have low thermal insulation capabilities so porous matrices with low thermal conductivities are often used to decrease the ...

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. ...

Carbon foams are novelty materials that have a wide range of applications such as radiators, thermal protection, and fire-resistant cores. The main carbon sources of carbon foams are sucrose, coal, coal tar pitch, and petroleum pitch, however the foams that use sucrose as their primary source have low thermal conductivity. This paper examined the thermal properties of carbon foams derived from sucrose but used graphite fillers to improve thermal conductivity. ...

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 ...
