Nanofluid has become popular with the advancement in nanotechnology. Nanofluid has comparatively better stability than the microfluid because here much smaller‐sized particles (nanometer size) are suspended in the base fluid. It has improved thermophysical properties and convective heat transfer coefficient than the base fluid alone. That is why researchers have implemented this novel heat transfer fluid in versatile fields. These are solar collectors, solar thermal energy storage, electronics cooling, cooling and heating, heat pipes, automobile radiator, refrigeration system, natural convection, quenching, and many other applications. These varied applications indicate that in imminent future nanofluid will play a major role in these fields. Though all these trials are at present at academic research level, however, with the advancement in nanotechnology, surface science, colloidal chemistry, and so forth this nanofluid will definitely play a major role in heat transfer in the coming days.

“…A correlation equation was proposed for laminar flow-see Table 2. Chiney et al [103] established that the addition of NPs may result in overall HTC improvement up to 54% under laminar flow in a double tube system. It was also found that the degree of intensification of the overall HTC decreased with the increase in the thermal conductivity of the heat transfer wall material.…”

A comprehensive review of published works dealing with experimental studies of forced convection heat transfer of nanofluids is presented. The survey is limited to straight, smooth, and round tubes. Moreover, only mono nanofluids exhibiting Newtonian behaviour are considered. Works on experimental research of forced convection in tubes are presented in a chronological order in the first part of the article. In this part, attention was paid to the influence of nanoparticles on the intensification of heat transfer. Information on the tested nanofluids, the measurement technique used, and the measurement range are presented in tabular form. Correlation equations proposed by individual researchers are also presented. In order to explain the controversy regarding the different influences of nanoparticles on the intensity of heat transfer during forced convection of nanofluids, the second part of the paper presents a comparison of the test results obtained by different researchers for the same nanofluid, possibly under the same thermal and flow conditions. Finally, the main conclusions are discussed.

Stable dispersions of nanoparticles in liquids are commonly referred to as nanofluids. The morphology of the dispersed nanoparticles can be quite diverse (spherical, tubular, etc), although one of the dimensions of the particles must usually be less than 100 nm. The liquid in which the particles are dispersed is commonly a heat transfer fluid such as water, oil, or ethylene glycol. Nanofluids have attracted much attention recently because of their unusual thermophysical and optical properties. In particular, the thermal conductivity of the heterogeneous mixture (liquid plus nanoparticles) has been shown to be significantly higher than that of the base liquid. This has led to numerous proposals for using nanofluids in demanding heat transfer applications such as solar thermal energy storage and microelectronics cooling. This article presents an overview of the properties of nanofluids, and also includes a discussion of their preparation and characterization. Particular emphasis is given to the thermal conductivity because of its importance in heat transfer, and because its dependence on particle size and temperature is still the subject of many studies. The article concludes with a discussion on promising directions for nanofluid research.
