Different methods have been utilized to enhance the thermal efficiency of the heat exchangers (HEs). A widely used method to upgrade the thermal efficiency of HEs is upgrading the thermal properties of working fluid by utilizing nanoparticles. In this study, Al 2 O 3 and CuO have been utilized to prepare Al 2 O 3-CuO/water hybrid nanofluid. Accordingly, Al 2 O 3 and CuO nanoparticles have been mixed into the water with 1% (50:50) weight concentration. The main objective of this work is testing the prepared hybrid nanofluid in plate-type HEs (PHEs) with 8, 12 and 16 plates to determine the influence of number of plates on heat transfer improvement by hybrid nanofluid. Experimental findings of the present study demonstrated that utilizing Al 2 O 3-CuO/water hybrid-type nanofluid in the PHE enhanced thermal efficiency notably in comparison with singletype nanofluids. Using this hybrid nanofluid increased the thermal performance in all PHEs with different number of plates. However, it is observed that increasing number of plates led to more increment in thermal performance by utilizing hybrid nanofluid. The highest increment in overall heat transfer coefficient was obtained as 12%, 19% and 20% in PHEs with eight, 12 and 16 plates, respectively. In addition, the highest enhancement in effectiveness was achieved as 10%, 11.7% and 16% in PHEs with eight, 12 and 16 plates, respectively.

“…Investigations were done with MWCNT/water HyNf in the plate heat exchanger, which resulted in improved thermal characteristics 10,11 . Bhattad et al 12 considered the influence of particle volume ratio for Al 2 O 3 –MWCNT/water HyNf and observed that MWCNT nanofluid gives the best performance. Bhattad et al 13 found that Al 2 O 3 –SiC HyNf as a cooling agent is best in terms of energy performance among different studied combinations.…”

Exergy-energy analysis of the plate heat exchanger is experimentally performed with different Al 2 O 3 -MgO hybrid nanofluid (HyNf) as a hot fluid. There were six combinations of fluids, namely, deionized (DI) water, ethylene glycol-DI water brine (1:9 volume ratio), propylene glycol-DI water brine (1:9 volume ratio), base fluids and their respective Al 2 O 3 -MgO (4:1 particle volume ratio) HyNfs of 0.1% total volume concentration. The effects of different flow rates and hot inlet temperatures on the heat transfer rate, heat transfer coefficient, pump work, irreversibility, and performance index (PI) are investigated. It is witnessed that the heat transfer rate, heat transfer coefficient, pump work, and irreversibility enhances with the flow rate and nanoparticle suspension. While the PI declines with a rise in the flow rate, the heat transfer rate, heat transfer coefficient, PI, and irreversibility rise up maximum for MgO-alumina (1:4) DI water HyNf upto 11.8%, 31.7%, 11.1%, and 4.05%, respectively. The pump work enhances upto 1.6% for MgO-alumina (1:4)/EG-DI water (1:9) HyNf.

An experimental investigation is conducted with graphene-Al 2 O 3 hybrid nanofluid as a coolant in corrugated surface plate heat exchanger to study energetic performance. The combinations studied are Al 2 O 3-graphene in 4:1 nanoparticle ratio and 100% Al 2 O 3 nanoparticle with 0.01 v % concentration in DI water. Effect of coolant flow rates (2.0-4.0 lpm) and coolant inlet temperatures (10-25 °C) on various factors like coolant outlet temperature, heat transfer rate, convective heat transfer coefficient, pressure drop, and heat transfer coefficient to pressure drop ratio has been investigated. Maximum enhancements of around 2.5%, 5.34%, 25.36%, and 23.8% are observed in the coolant outlet temperature, heat transfer rate, heat transfer coefficient, and heat transfer coefficient to pressure drop ratio, respectively, for Al 2 O 3-graphene hybrid nanofluid.
