    Analyses of entropy generation and pressure drop for a conventional flat plate solar collector using different types of metal oxide nanofluids
    (ELSEVIER SCIENCE SA, 2013) M. A. Alim; Z. Abdin; R. Saidur; A. Hepbasli; M. A. Khairul; N. A. Rahim; Abdin, Z.; Alim, M. A.; Khairul, M. A.; Hepbasli, A.; Saidur, R.; Rahim, N. A.
    This paper theoretically analyzes entropy generation heat transfer enhancement capabilities and pressure drop of an absorbing medium with suspended nanoparticles (Al2O3 CuO SiO2 TiO2 dispersed in water) inside a flat plate solar collector. Steady laminar axial flow of a nanofluid is considered. These nanofluids considered have different nanoparticles volume fractions and volume flow rates in the range of 1-4% and 1-4 L/min respectively. Based on the analytical results the CuO nanofluid could reduce the entropy generation by 4.34% and enhance the heat transfer coefficient by 22.15% theoretically compared to water as an absorbing fluid. It also has a small penalty in the pumping power by 1.58%. (C) 2013 Elsevier B.V. All rights reserved.
