“…They concluded that the combined use of nano-fluid and helical coil will noticeably increase the Nu number. Akbaridoust et al [10] conducted an experimental and numerical investigation of CuO nano-fluid inside helical coils at constant temperature surface. Using the single-phase homogeneous approach and effective properties in this study resulted in a numerical estimation underestimating the experimental results.…”

“…and dimpled tube have own benefits of lower pressure drop, less cost, easy installation and removal (Chandrasekar et al 2010;Suresh et al 2012;Saeedinia et al 2012;Hashemi & Akhavan-Behabadi 2012;SyamSundar et al 2012;Akbaridoust et al 2013;Kannadasan et al 2012). For augmentation of heat transfer rate MWCNT is a promising candidate in specified base fluid because it has shear thinning behaviour at boundary layers so it increases the thermal conductivity which is solely contributes to heat transfer rate (Garg et al 2009;Amrollahi et al 2010;Liu & Liao 2010;Akhavan-Behabadi et al 2012;Wang et al 2013;Ashtiani et al 2012;Fakoor-Pakdaman et al 2013;Kumaresan et al 2012;Kumaresan et al 2013).…”

Nanofluids are suspension of nanoparticles (less than 100 nm) in the conventional base fluids. The dispersed solid metallic or non-metallic nanoparticles change the thermal properties like thermal conductivity, viscosity, specific heat, and density of the base fluid. Past studies focused on measuring the thermal properties of nanofluids. These suspended nanoparticles effectively improve the transport properties and heat transfer characteristics of the base fluids. Recently, heat transfer augmentation using suspensions of nanometre-sized solid particles in base liquids have been investigated by various research groups across the world. This paper reviews the state-of-the-art nanofluid studies in the area of forced convection heat transfer enhancement. The results for the heat transfer characteristics in internal flow with constant heat flux and constant wall temperature boundary conditions reported by various researchers have been compiled and reviewed. Further, in heat exchangers, the real boundary conditions are different from the constant heat flux and constant wall temperature boundary conditions. Over a span of 2 decades, the literature in this field is widespread; hence, this review would be useful for researchers to have a precise screening of a wide range of investigations in this area.
