Irreversibility analysis and thermal radiative of Williamson (ZnO+MOS ₂/C ₃ H ₈ O ₂) hybrid nanofluid over a porous surface with a suction effect

Abstract

The current approach considered the suction/inject flow of a Williamson hybrid nanoliquid in porous medium under the effect of the thermal radiative flow towards a convectively heated streching sheet. propylene glycol (PG) (C_3 H_8 O_2) is employed as the base liquid in this study, and the nanoparticles are Molybdenum disulfide (MOS_2)and Zinc Oxide (ZnO). The primary contribution of this study is to discuss heat transmission via thermal radiation, suction/injection, and the porous parameter on the flow of a William hybrid nanoliquid. The current problem is evaluated using the connective and suction/injection, and it is moedlled using higher-order nonlinear PDEs that are turned into highly nonlinear ODEs using the similarity transformation method. The Bvp4c technique is used on these generating ODEs for the mumerical technique in the methodology section. In the discussion section, the significant of several flow parameters on the velocity, energy, entropy generation and Bejan number of the hybrid nanofluid are plotted against various flow parameters. A significant drop in the velocity field is supported by the WilliamsonWe, Unsteadyβ, and porosityγ factors. The temperature profile is significantly raised by the Biot numberBi, thermal radiationRd, and suction factorS.Moreover, it has been found that entropy increases with radiationRd but reduces in Brinkman number Br against the bejan number profile.The analysis of physical quantities requires the use of numerical data. Our results for a few specific situations were compared with previously published data to establish the validity of the current study, and it was discovered that they were in strong agreement
