Abstract

Encyclopedia Ionic liquids have proven to be one of the most impressive fluid classes due to their specific properties and applications in chemistry and energy engineering. One of the most recent applications of the ionic liquids is the manufacture of ionanofluids. These new materials are a particular type of nanofluid and are defined as a stable dispersion of nanomaterial particles (tubes, rods, spheres) in an ionic liquid.Ionanofluids are an innovative research field also due to the increasing need to identify non-pollutant heat transfer environments while reducing energy consumption.It is clearly demonstrated in the literature that, despite the inconsistent data, substantial increases in the thermal characteristics of this particular type of nanofluids as compared to their basic fluids are unquestionable.However, published data are still limited and scattered, and are insufficient to understand clearly the mechanisms of these new fluids heat transfer. It is therefore impetuous to carry out more comprehensive studies of their heating behavior under different conditions or factors such as: concentration, temperature, pressure, flow conditions, heating systems and flow geometry. The numerical research on ionanofluids it is still at its beginnings. Therefore, some ionanofluids were implemented in several codes to analyze their behavior in heating systems and associated results are very interesting in demonstrating possible uses for heating.In this paper the authors will try to implement some fully described ionanofluids in a numerical code to get information about the ionanofluids behavior in laminar flow conditions. The implemented ionanofluids will be based on a mixture of water and ionic liquid in three different mole fractions and alumina nanoparticles will be added.Concluding, research on ionanofluids is very important and great efforts are needed to fully describe these new heat transfer fluids and to explore their potential in applications.
