The effect of ternary hybrid nanofluids at varied mixing ratios is not considered in the studies by utilizing an optimization approach that saves time and process. In the current study, the Taguchi approach is used for single-objective optimization and grey relation analysis is used for multi-objective optimization to indicate an enhancement of the thermal and hydraulic characteristics of a circular tube using ternary hybrid nanofluids. The selected design factors encompass all relevant physical characteristics, such as the mass ratios (0.1, 0.2, 0.3, 0.4 and 0.5) of GnP, MWCNT and Fe3O4 nanoparticles and the input variable Reynolds number range from 10,000 to 30,000. The Taguchi results show that the Nusselt number is best achieved by the highest level of the four parameters, whereas the friction factor is primarily motivated by the lowest mass ratios of the nanoparticles. The analysis of variance outcome also demonstrates that the highest contribution to the Nusselt number and friction factor at constant pumping power is provided by GnP nanoparticles, followed by MWCNT and FE3O4, respectively. The configuration with a Reynolds number of 30,000, 0.4 mass% GnP, 0.3 mass% MWCNT and 0.2 mass%FE3O4 is found to possess the optimum thermal and hydraulic characteristics utilizing grey relational analysis.
