“…The heat transfer improvement on the thermal performance of the shell and tube heat exchanger by the use of Al 2 O 3 /water and TiO 2 /water nanofluids was studied. The maximum heat transfer coefficient enhancement achieved by Al 2 O 3 /water was 41%, while the maximum heat transfer coefficient using TiO 2 /water was 37% [275]. Further studies related to the application of nanofluids in heat exchangers are presented in Table 8.…”

“…Sarafraz et al used a low-frequency vibration, which improved the heat exchanger’s thermal performance. The latest research work in STHEx revealed that nanofluids containing different types of nanoparticles such as Ag, CuO, Al 2 O 3 , TiO 2 , and graphene oxide outperformed their respective base fluids in terms of thermal performance. Nazarzade et al experimentally explored the forced convective heat transfer in STHEx with a silver/water nanofluid.…”

“…An Al 2 O 3 /water nanofluid was revealed to be a better cooling medium than distilled water in the study; however, the use of an Al 2 O 3 /water nanofluid as a cooling medium increased the pressure drop on the tube side in comparison to the distilled water. Ullah et al 239 numerically investigated the heat transfer properties of TiO 2 /water and γ-Al 2 O 3 /water nanofluids in the STHEx. The influences of the Reynolds's number of suspended nanoparticle vol % and particle type were examined on the thermal properties.…”

“…The thermal conductivity of the hybrid NFs may be larger or smaller than that of mono NFs and proper selection of NPs of hybrid NFs plays an important role to achieve higher stability of NFs. Besides, many types of research have been done to synthesize the heat transfer capacity of the hybrid NFs [29][30][31][32][33][34]. Fig.…”
