Special Issue Information

Dear Colleagues,

In the last two decades we are witnessing a deep evolution of lubricants and heat transfer fluids due to the dispersion of different nanoadditives. These dispersions have received increasing attention because of their potential in energy systems. This field is multidisciplinary and includes many complex phenomena and processes that are really encouraging and stimulating to investigate. To date, the foremost challenge for developing a new nanolubricant or nanofluid is to achieve stable suspensions in the currently used base fluids or lubricant base oils. In order to solve this issue, the studies about the use of classical nanoparticles as metals and metal oxides have evolved to more complex nanoparticles and one and two dimensional nanomaterials with coated surfaces among other structural changes for both applications. Nano additive synthesis as well as nanodispersion preparation and the thermophysical, tribological, optical and rheological characterization of both nanomaterials as proposed new materials are necessary studies to suggest next-generation applications of nanomaterials with outstanding performances in industrial applications, renewable energies and automotive engines in particular.

This Special Issue is aimed at providing significant contributions on advances in dispersions including the manufacture and characterization of nanolubricants as well as nanofluids for heat transfer and storage of thermal energy focusing on potential industrial applications and renewable energies in particular. New studies about advances nanoadditives as coated nanoparticles, hybrid nanoparticles, two-dimensional and one-dimensional nano additives, are also welcomed. Synergies studies with other nanoadditives used in the current formulations are expected. Original high-quality research papers dealing with complete experimental analysis, molecular simulations or theoretical advances covering the most recent advances as well as comprehensive reviews addressing state-of-the-art topics in the field will be considered for publication.

Adding nanoparticles to liquid fuel is known to promote its combustion characteristics through improving several thermo-physical properties. This study investigates the effects of adding carbon nanoparticles on thermal conductivity and evaporation rate of liquid jet fuel. Multi-walled carbon nanotubes, activated carbon nanoparticles, and graphene nanoplatelets were added to jet fuel at different concentrations to prepare colloidal suspensions. Thermal conductivity is determined by passing known amounts of heat through a very thin layer of fuel and measuring temperature difference across its thickness. A fiber-supported droplet technique is also used to evaluate evaporation rate due to force convection of a hot inert gas. It is observed that both thermal conductivity and evaporation rate increase as a result of nanoparticle addition. Since there is no radiation heat transfer mechanism, the increase in evaporation rate is concluded to be only due to enhanced thermal conductivity. Full article
