Irreversibility and thermal performance of nonlinear radiative cross-ternary hybrid nanofluid flow about a stretching cylinder with industrial applications

Significance: The suspension of nanoparticles in the base fluid has significant attention from researchers and industries with an aspect of improving the thermo-physical properties of the fluid. The significance is more prominent for ternary hybrid nanofluids by improving energy production, storage and efficiency, and play a huge role in global sustainable energy development and cleaner energy production. Aim: The aim of the present problem is to analyze the flow and thermal behavior of a cross -ternary SWCNT, MWCNT, and GO nanoparticles composite water -based ternary hybrid nanofluid past a stretched cylinder. Thermal expansion phenomena feature joule heating and non-linear thermal radiation under convective conditions. Research methodology: Transformed nonlinear equations are solved numerically by the homotopy analysis method. The flow feature with the physical interest quantities such as skin friction and Nusselt number has been displayed through graphs and tables. Further, the optimized entropy of the system with the Bejan number has been discussed and displayed through graphs and tables. A comparison was made with the existing literature. Each graph features a comparison of ternary hybrid, hybrid, and mono nanofluid with other significant physical parameters. Major conclusion: Entropy generation is observed to nonlinearly slow down with improvements in the Brinkman and radiation parameters, while a reverse procedure develops for the Bejan number with the above parameters. An improvement in Weissenberg and curvature parameters accelerates the fluid velocity and heat transfer rate, while fluid motion is controlled by an increase in magnetic field strength. Outcomes may help to understand the performance of the ternary hybrid nanofluids applications in different industries under certain circumstances.
