Various concentrations of nanoparticles in water and water/glycol, from 250ppm to 3000ppm, were examined for volume fraction impact. Results indicate that the laboratory tests were different from those under real conditions because of the high concentration of nanoparticles used in laboratory tests; however, by using nanofluid (even with low concentrations around 0.3) solar collector efficiency improved (3.2).Results have also shown that the use of copper nanofluid in ethylene glycol as the base fluid causes a significant reduction in collector efficiency, due to the increase in viscosity. However, using higher flow rates caused the heat transfer rate to rise because of increased turbulence. © 2014 Owned by the authors, published by EDP Sciences. date: 2014 publisher: EDP Sciences official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84904959187&doi=10.1051%2fmatecconf%2f20141302014&partnerID=40&md5=c5625aba5f57fe009e895c1270ad70b9 id_number: 10.1051/matecconf/20141302014 full_text_status: none publication: MATEC Web of Conferences volume: 13 place_of_pub: Kuala Lumpur refereed: TRUE issn: 2261236X citation: Assadi, M.K. and Nasersharifi, Y.
