Resumo
Ionic liquids have been suggested as new engineering fluids, specifically in the area of\\\\nheat transfer, and as alternatives to current biphenyl and diphenyl oxide, alkylated aromatics and\\\\ndimethyl polysiloxane oils, which degrade above 200 ?C, posing some environmental problems.\\\\nAddition of nanoparticles to produce stable dispersions/gels of ionic liquids has proved to increase\\\\nthe thermal conductivity of the base ionic liquid, potentially contributing to better efficiency of heat\\\\ntransfer fluids. It is the purpose of this paper to analyze the prediction and estimation of the thermal\\\\nconductivity of ionic liquids and IoNanofluids as a function of temperature, using the molecular\\\\ntheory of Bridgman and estimation methods previously developed for the base fluid. In addition,\\\\nwe consider methods that emphasize the importance of the interfacial area IL-NM in modelling the\\\\nthermal conductivity enhancement. Results obtained show that it is not currently possible to predict\\\\nor estimate the thermal conductivity of ionic liquids with an uncertainty commensurate with the\\\\nbest experimental values. The models of Maxwell and Hamilton are not capable of estimating the\\\\nthermal conductivity enhancement of IoNanofluids, and it is clear that the Murshed, Leong and Yang\\\\nmodel is not practical, if no additional information, either using imaging techniques at nanoscale or\\\\nmolecular dynamics simulations, is available.
