A nanofluid with developed and advanced high temperature heat transfer is crucial for the enhancement of concentrated solar power (CSP) efficiency, and consequently, the cost reduction of electricity production. Incorporation of metallic nanoparticles into heat transfer fluids used in CSP application could result in nanofluids with improved thermal transport properties. This study reports on the synthesis and investigation of silver nanowires (AgNWRs) based nanofluids synthesized by the polyol process in ethylene glycol (EG) as a reductant, polyvinylpyrrolidone (PVP) as structure-directing agent for the growth of Ag nanowires. Structural and morphological characterisations revealed highly crystalline three-dimensional (3D) interconnected network of Ag nanowires. EGbased suspensions in the presence of various AgNWRs loadings (0.5â??2 vol.%) were prepared and thermal conductivity measurements were conducted. A thermal conductivity enhancements over the EG base fluid of 30% at a 2 vol.% AgNWRs loading was achieved.
