Summary
Science is fundamental to support technology developments, namely in the area of nanosystems, by using nanomaterials (CNT’s, graphene, natural melanin) to enhance the thermal properties of base engineering fluids, which have to be measured by rigorous instrumental methods. The new trends for the evolution of our society and namely our economy, require that future industrial and domestic uses sustainable chemicals, free of environment and human risks, but necessarily efficient in heat transfer and storage.\n\nThe possible use of nanomaterials and nanosystems as alternative heat transfer fluids require the development of a strategy for their production, use and disposal, involving environmental and safety requirements, which can restrict the a priori selected systems. Therefore, the implementation of a regulatory framework, a driving force for nanotechnologies development, is essential for the acceptance by society. A strategy to select a given nanofluid or IoNanofluid for a given application, bound by the environmental and safety regulatory frameworks, was recently proposed1 and will be extended to the LCA of a product and its contribution to UN Sustainable Development Goal 132.\n\nThe context of using nanofluids (stable dispersions of nanomaterials in molecular fluids or ionic melts) as alternative heat transfer fluids will be analysed, exemplifying technically with the determination of heat transfer coefficients in a selected heat exchanger (concentric tube), using a promising new ionic liquid and their mixtures with water as the base fluid, [C2mim][CH3SO3] (ST35™, BASF), for which their thermophysical properties were recently determined3,4. The nanomaterial used was a natural melanin, obtained from cuttlefish, and previously demonstrated to increase significantly the efficiency of thermal storage in a pilot solar collector1,5.\nReferences\n1.
