By a News Reporter-Staff News Editor at Energy Weekly News -- New research on Nanofluids is the subject of a report. According to news reporting originating from Argonne, Illinois, by VerticalNews correspondents, research stated, "Novel high-temperature heat transfer fluids (HTFs) with incorporated phase change nanomaterials were synthesized and tested for heat transfer and thermal energy storage. The advanced thermal properties were achieved by preparing a nanofluid consisting of core/shell silica encapsulated tin (Sn/SiO2) nanoparticles dispersed in a synthetic HTF Therminol 66 (TH66) at loadings up to 5 vol%."
Our news editors obtained a quote from the research from Argonne National Laboratory, "Tin nanoparticles were synthesized by modified polyole reduction method followed by sol-gel silica encapsulation process. The measured increase in thermal conductivity of the nanofluid (13% at 5 vol%) was in agreement with Maxwell's effective medium theory. Latent heat of phase change during melting of Sn core added 11% increase to the volumetric thermal energy storage of the nanofluid when cycled in between 100 degrees C and 270 degrees C. The value could be further improved if thermal cycling is conducted in a narrower temperature range. The experimental results demonstrated dual functionality of the engineered nanofluids as desired for Concentrated Solar Power systems."
According to the news editors, the research concluded: "Viscosity and stability of the nanofluids as well as thermal stability of core/shell nanomaterials) were investigated in a wide temperature range to obtain a perspective on any additional pumping power requirements for the nanofluid over the base fluid."
