The improvement in heat transfer equipment plays a significant role to enhance the overall performance of many systems and wide variety industrial processes. Heat exchangers are widely used these applications with aim limiting growing energy demand further is needed. A low-enthalpy geothermal system commonly constituted by ground exchanger, pump unit, indoor heating/cooling units. In exchanger circuit, exchange occurs between fluid wellbore through tubular section similar that inner tube...
The lack of a standard experimental procedure to determine thermal conductivity fluids is noticeable in heat transfer processes from practical and fundamental perspectives. Since wide variety techniques have been used, reported literature data huge discrepancies. A common practice using manufactured meters for nanofluids, which can standardize the measurements but are also somewhat inaccurate. In this study, new methodology perform reliable with recent commercial transient hot-wire device...
Geothermal heat pump systems in residential and commercial applications have become popular many countries over the past years. The transfer performance of ground exchangers these has still room for improvement since they huge influence on overall efficiency. Likewise, new fluids with enhanced properties, known as nanofluids, been proposed a potential solution to substitute conventional working improve processes performance. A reliable appropriated proposal nanofluids particular application...
Thermal energy storage (TES) facilitates the integration of renewable by decoupling production and consumption, mitigating intermittence issues. However, current TES systems use fossil fuel-based products as media, so development sustainable efficient materials should be investigated. This work aims to design characterization new eco-friendly nanoenhanced phase change (NePCMs) based on dispersions graphene nanoplatelets two different lateral sizes (7.2 40 μm) in isopropyl palmitate for cold...
This research aims to evaluate the efficacy of Mouromtseff’s numbers in assessing thermal transfer performance titanium oxide (TiO2) nanosized dispersions convective heat through a pipe. New experimental coefficients transfer, thermophysical and rheological characterisation are carried out for TiO2-based nanodispersions an aqueous propylene glycol 30 vol% mixture at various nanoadditive mass loadings (from 0.25 2.0 wt%). Different number formulations, including Dittus–Boelter Simons...
The thermal properties of graphene have proved to be exceptional and are partly maintained in its multi-layered form, nanoplatelets (GnP). Since these carbon-based nanostructures hydrophobic, functionalization is needed order assess their long-term stability aqueous suspensions. In this study, the convective heat transfer performance a polycarboxylate chemically modified GnP dispersion water at 0.50 wt% experimentally analyzed. After designing nanofluid, dynamic viscosity, conductivity,...

A comprehensive study has been performed on the thermal and rheological behaviour of two sets isooctyl stearate (PureTemp 8, PT8) based nanofluids with different concentrations spherical MgO nanoparticles (up to 15 wt%) graphene nanoplatelets 2 wt%). The results show that presence nanomaterials does not significantly alter phase change temperatures base fluids, although latent heat decreases by 27% 7.6% for wt% 1.0 GnP-based nanofluids, respectively. Both are found increase diffusivity...
