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.

“…Because of higher thermal conductivity and efficiency of nanofluids, smaller and compact design of solar thermal collectors has become possible without affecting the output desired. Smaller size collector can reduce the material usage, cost, and energy required in manufacturing (Leong et al 2012). Some studies were made on the potential of size reduction of various engineering applications using nanofluids.…”

“…Some studies were made on the potential of size reduction of various engineering applications using nanofluids. These were based on vehicle's weight reduction (Saidur and Lai 2011), building heat exchanger's heat transfer area (Kulkarni et al 2009), reduction of air frontal area of a car radiator (Leong et al 2010), and the size reduction of shell and tube recovery exchanger (Leong et al 2012). Other studies had also been made to evaluate the economic and environmental impact of solar hot water system (Kalogirou 2004(Kalogirou , 2008Tsillingiridis et al 2004;Ardente et al 2005).…”

To overcome the environmental impact and declining source of fossil fuels, renewable energy sources need to meet the increasing demand of energy. Solar thermal energy is clean and infinite, suitable to be a good replacement for fossil fuel. However, the current solar technology is still expensive and low in efficiency. One of the effective ways of increasing the efficiency of solar collector is to utilize high thermal conductivity fluid known as nanofluid. This research analyzes the impact on the performance, fluid flow, heat transfer, economic, and environment of a flat-plate solar thermal collector by using silicon dioxide nanofluid as absorbing medium. The analysis is based on different volume flow rates and varying nanoparticles volume fractions. The study has indicated that nanofluids containing small amount of nanoparticles have higher heat transfer coefficient and also higher energy and exergy efficiency than base fluids. The measured viscosity of nanofluids is higher than water but it gives negligible effect on pressure drop and pumping power. Using SiO 2 nanofluid in solar collector could also save 280 MJ more embodied energy, offsetting 170 kg less CO 2 emissions and having a faster payback period of 0.12 years compared to conventional water-based solar collectors.
