Analyses of entropy generation and pressure drop for a conventional flat plate solar collector using different types of metal oxide nanofluids
(Energy and Buildings, 2013)
This paper theoretically analyzes entropy generation, heat transfer enhancement capabilities and pressure drop of an absorbing medium with suspended nanoparticles (Al2O3, CuO, SiO2, TiO 2 dispersed in water) inside a flat ...
Effect of nanoparticle shape on the heat transfer and thermodynamic performance of a shell and tube heat exchanger
(International Communications in Heat and Mass Transfer, 2013)
Nanofluid is a heat transfer fluid that can improve the performance of heat exchanger systems. Different parameters such as particle size, shape, and volume concentration affect the performance of these systems. The objective ...
Experimental investigation of the relation between yield stress and ultrasonication period of nanofluid
(PERGAMON-ELSEVIER SCIENCE LTD, 2016)
Nanofluids are the mixtures of solid nanoparticles in liquid. Like most other fluids, nanofluids could behave as yield stress fluids, which require a certain amount of stress to flow. This flow characteristic may depend ...
