A new relationship on transport properties of nanofluids. Evidence with novel magnesium oxide based n-tetradecane nanodispersions
Prado, José I.; Vallejo, Javier P.; Lugo, Luis (Powder Technology, 397 (2022) 117082, 2022-02-03)The worldwide increasing of thermal energy consumption fosters new technological solutions based on nanomaterials. The use of nanofluids enhances energy efficiency leading to eco-friendlier devices. Thus, researchers are ... -
Analysis of Heat Transfer Characteristics of a GnP Aqueous Nanofluid through a Double-Tube Heat Exchanger
Calviño, Uxía; Vallejo, Javier P.; Buschmann, Matthias H.; Fernández-Seara, José; Lugo, Luis (Nanomaterials 2021, 11(4), 844, 2021-03-25)The thermal properties of graphene have proved to be exceptional and are partly maintained in its multi-layered form, graphene nanoplatelets (GnP). Since these carbon-based nanostructures are hydrophobic, functionalization ... -
Hybrid or mono nanofluids for convective heat transfer applications. A critical review of experimental research
Vallejo, Javier P.; Prado, José I.; Lugo, Luis (Applied Thermal Engineering 23, 25 february, 117926, 2021-12-11)Research on nanofluids has increased markedly in the last two decades. Initial attention has focused on conventional or mono nanofluids, dispersions of one type of solid nano-sized particles in a base fluid. Despite various ... -
Thermophysical, rheological and electrical properties of mono and hybrid TiB2/B4C nanofluids based on a propylene glycol:water mixture
Vallejo, Javier P.; Zyla, Gawel; Ansia, Lucas; Fal, Jacek; Traciak, Julian; Lugo, Luis (Powder Technology 395 (2022) 391-399, 2021-09-30)Hybrid nanofluids aim to further improve the characteristics of mono nanofluids. However, experimental studies that jointly explore the physical properties of hybrids and the corresponding mono nanofluids are missing. In ... -
Tuning the thermal properties of aqueous nanofluids by taking advantage of size-customized clusters of iron oxide nanoparticles
Elsaidy, Amir; Vallejo, Javier P.; Salgueiriño, Verónica; Lugo, Luis (Journal of Molecular Liquids 344 (2021) 117727, 2021-10-05)In this study, the thermal conductivity of aqueous nanofluids containing clusters of iron oxide (Fe3O4/γ-Fe2O3) nanoparticles has been investigated experimentally for the first time, with the aim of assessing the role of ...
