“…have a higher value of k than that of the base or conventional fluid even at their low volume fraction (φ) in the base fluids (Kakaç and Pramuanjaroenkij, 2009). Suspension of the NP in the base fluids also affects the other properties of the fluids along with k. Moreover, the addition of the NPs causes more pressure drop which results in a penalty in terms of the pumping power (Wu et al, 2016;Malvandi et al, 2017). Thermophysical properties of some of NPs, base fluids and NFs are given in Table 3, which were used by researchers in their studies.…”

This work presents a detailed review of the entropy generation due to the heat transfer and the fluid flow through different channels. The earlier contribution of the researchers in the form of theoretical, numerical and experimental studies on the entropy generation in the conventional or microchannels, with or without disruption in the flow and with or without the use of nanofluids is reviewed. The brief discussion on the microchannels, disrupted microchannels, nanofluids and entropy generation is presented. Studies performed on the channel cross-sectional shapes and rib shapes for thermal performance optimisation are discussed in the paper. Nanoparticles such as Al2O3, Cu, CuO, Ag, SiO2, etc. have been used for preparing the nanofluids along with water, ethylene glycol, etc. as base fluids. Additionally, the effect of disruption in flow field on the entropy generation is also discussed. The disruptions in the form of ribs, cavities, vortex generators, etc. have been taken into account. It is hoped that this review article can provide a basis for further research on the irreversibility analysis of the nanofluid flowing through disrupted microchannels to improve the hydrodynamic and thermal performance of the system.
