“…Sonawane et al [50] investigated specific heat of Al 2 O 3 /ATF and reported the anomalous behavior of specific heat with volume concentration. Increase in specific heat capacity has been reported in experimental observations [48,[51][52][53][54][55][56][57]. Pakdaman et al [58] observed 21-42% decrease in specific heat capacity of MWCNT/water nanofluid for 0.1-0.4% vol.…”

“…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). From the above review, the maximum enhancement of 190% in heat transfer as compared to de-ionized water was observed by Wang et al (2013) at 0.24 vol.%.…”

“…%. Yet again, similar investigation was accomplished by Kumaresan et al (2013) with the similar heat exchanger of several lengths for energy efficient cooling/heating system. In contrast to conventional heat transfer concept, the value of the Nusselt number for the nanofluids showed increment with the fall in the Reynolds number as the MWCNT concentration growths.…”

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.

“…Their results showed an enhancement of 7%-202% compared to water which they attributed to high thermal conductivity and surface area of CNT nanoparticles. Kumaresan et al (2013) performed an experiment to study convective heat transfer characteristics of multi-walled nanofluids including carbon nanotubes and a mixture of water and ethylene glycol as base fluid in a shell and tube heat exchanger. Volume concentration was in the pure water to 0.45% range.…”

This paper focuses on the nanofluids implementation in the tubular heat exchangers namely, shell and tube, double pipe and coiled tube. The author thinks that a comprehensive review of performed studies in this area can demonstrate advantages and disadvantages of nanofluids application in the heat exchangers. All available papers are reflected in this paper including experimental and numerical studies with all of their important features and findings. The most considered paper confirmed the Nusselt number enhancement with the use of nanofluids in the heat exchangers. Also, nanofluids implementation in the heat exchangers resulted in an increase in the required pumping power, in the most cases.
