Summary
Ionanofluids are the suspensions of nanoparticles in ionic liquids. Although the field of ionic liquids (IL) is relatively well-established and have received wide interest, ionanofluids which is a recently devised area comprising of both IL and nanofluids fields, has not yet well known. Most of the reported studies on this new fluids dealt with experimental measurements of thermal properties particularly thermal conductivity and results are promising as considerably higher thermal conductivity of ionanofluids compared to base IL were observed [e.g., 1-3]. However, the actual heat transfer mechanisms are not well-understood at this moment and the measured thermal conductivity of ionanofluids cannot be predicted by the popular classical models such as Maxwell [4] and Hamilton and Crosser [5] models. Although many studies were devoted to identify the heat transfer mechanisms and to develop models for nanofluids [6-7], no efforts have so far been reported on the development of model for the thermal conductivity of ionanofluids. In an effort to predict the thermal conductivity of ionanofluids these classical models [4-5] as well as models previously developed for nanofluids [7] are used. While the classical models under predict the thermal conductivity of ionanofluids, the nanolayer-based Murshed et al.´s model [7] better predict the results with adjustable parameters. By analyzing possible mechanisms and comparing experimental and predicted results this study demonstrates that these models are not conclusively capable of predicting the thermal conductivity of wide range of ionanofluids.
