Special Issue Information

Dear Colleagues,

Since the early 1990s, nanofluids have received growing attention because of their potential as heat transfer fluids in energy systems due to their enhanced thermal properties induced by the presence of nanoparticles. Nanofluid science is multidisciplinary and involves many complex phenomena and processes that are really motivating and challenging to investigate.

This Special Issue of Nanomaterials aims to publish original high-quality research papers covering the most recent advances as well as comprehensive reviews addressing state-of-the-art topics in the field of nanofluids and related materials.

Also, opinions and papers on open questions that could give critical assessments and future directions in this research field are welcome.

This Special Issue will cover the synthesis, preparation, and characterization of both nanomaterials and associated nanofluids, focusing on the next-generation applications of nanomaterials with outstanding performances in terms of stability, thermophysical properties, and heat transfer behavior relevant for industrial applications. The development of new theoretical and physical models, as well as simulations closer to practical situations, are also expected.

Topics to be covered by this Special Issue include, but are not limited to, the following:

  • Nanomaterials and Nanofluids preparation and characterization (nanoparticles, nanoPCM, nanofluids, nanosalts, ionanofluids, etc.)
  • Measurements and theoretical development of Nanofluid properties
  • Measurements and theoretical development of Nanofluid heat transfer
  • Experimental and theoretical analysis on nanofluid transport in porous media
  • Measurements and theoretical development of Nanoparticle-enhanced phase change materials
  • Numerical simulations relevant for potential applications
  • New numerical models for estimation of nanofluids heat transfer behavior
  • New innovative areas of nanofluid applications
  • Critical assessments and future directions in Nanofluids research

In advance, we would like to gratefully acknowledge the authors and reviewers who will participate to the elaboration of this Special Issue and that will contribute to the development of nanofluid research.

This paper presents results of experimental investigation into dielectric properties of silicon oxide lignin (SiO2-L) particles dispersed with various mass fractions in ethylene glycol (EG). Measurements were conducted at a controlled temperature, which was changed from 298.15 to 333.15 K with an accuracy of 0.5 and 0.2 K for dielectric properties and direct current (DC) electrical conductivity, respectively. Dielectric properties were measured with a broadband dielectric spectroscopy device in a frequency range from 0.1 to 1 MHz, while DC conductivity was investigated using a conductivity meter MultiLine 3410 working with LR925/01 conductivity probe. Obtained results indicate that addition of even a small amount of SiO2-L nanoparticles to ethylene glycol cause a significant increase in permittivity and alternating current (AC) conductivity as well as DC conductivity, while relaxation time decrease. Additionally, both measurement methods of electrical conductivity are in good agreement. Full article

Convection heat transfer coefficients and pressure drops of four functionalized graphene nanoplatelet nanofluids based on the commercial coolant Havoline® XLC Pre-mixed 50/50 were experimentally determined to assess its thermal performance. The potential heat transfer enhancement produced by nanofluids could play an important role in increasing the efficiency of cooling systems. Particularly in wind power, the increasing size of the wind turbines, up to 10 MW nowadays, requires sophisticated liquid cooling systems to keep the nominal temperature conditions and protect the components from temperature degradation and hazardous environment in off-shore wind parks. The effect of nanoadditive loading, temperature and Reynolds number in convection heat transfer coefficients and pressure drops is discussed. A dimensionless analysis of the results is carried out and empirical correlations for the Nusselt number and Darcy friction factor are proposed. A maximum enhancement in the convection heat transfer coefficient of 7% was found for the nanofluid with nanoadditive loading of 0.25 wt %. Contrarily, no enhancement was found for the nanofluids of higher functionalized graphene nanoplatelet mass fraction. Full article

This review discusses exclusively the recent research on electrical conductivity of nanofluids, correlations and mechanisms and aims to make an important step to fully understand the nanofluids behavior. Research on nanoparticle-enhanced fluids’ electrical conductivity is at its beginning at this moment and the augmentation mechanisms are not fully understood. Basically, the mechanisms for increasing the electrical conductivity are described as electric double layer influence and increased particles’ conductance. Another idea that has resulted from this review is that the stability of nanofluids can be described with the help of electrical conductivity tests, but more coordinated research is needed. The purpose of this article is not only to describe the aforementioned studies, but also to fully understand nanofluids’ behavior, and to assess and relate several experimental results on electrical conductivity. Concluding, this analysis has shown that a lot of research work is needed in the field of nanofluids’ electrical characterization and specific applications. Full article
