the term nanofluids was first coined by sir stephen choi in 1995 at argonne national laboratory ,u.s.a .since the discovery, nanofluid have been explored as heat transfer fluids. nanofluids increased the thermal conductivity of existing coolants (water, ethylene glycol) by a magnitude of hundred times which made them attractive for miniaturization of electronic devices .from 1995 till 2008 nano...

In this paper a numerical investigation is performed to study the effects of different nanofluids on convective heat transfer enhancement in a partitioned square cavity subject to different shapes of nanoparticle using water-SiO2 nanofluid. This study has been carried out to analyze the effects of SiO2 nanoparticle, its volumetric fraction between 2 and 4%, and nanoparticle shape (i.e. blades, ...

Heat transfer including heat conduction, thermal convection, and radiation is a major transport process that occurs in various engineering natural systems such as exchangers, solar collectors, nuclear reactors, atmospheric boundary layers, electronical biomedical systems, others [...]
