Project Description

It is well known now the concept of nanofluids in the open literature. The necessity of developping new fluids (i.e. nanofluids – fluids with nanoparticles in suspension) came from the fact that heat-carrying fluids used in heat transfer applications have much lower thermal conductivity compared to solid materials, and nanofluids, even at extremely low concentrations, considerably improve heat transfer. IoNanofluids are innovative fluids, based on the nanofluid concept, defined as stable dispersion of nanoparticles in an ionic liquid, being called by some authors nanoparticle-enhanced ionic liquids (NEIL). To understand the behavior of IoNanofluids we need to understand not only the interactions between nanoparticles, ionic liquid ions, but also the interaction between ions and nanoparticles. At the same time, the success of the preparation of such a fluid depends on the method of preparation and the purity of the raw materials. Some of the most remarkable characteristics of all types of nanofluids are related to their improved thermal properties, but also other properties such as low density, permeability, electrical conductivity, etc. Thus, their correct characterization is extremely important for state of the art. Concluding, this project aims to produce and characterize new ionic liquids with the addition of nanoparticles, as well as to evaluate their behavior in a heat transfer application and is a logical continuation of this applicant doctoral thesis.
