Analytical Assessment of (Al2O3-Ag/H2O) Hybrid Nanofluid Influenced by Induced Magnetic Field for Second Law Analysis with Mixed Convection, Viscous Dissipation and Heat Generation

The current study is an attempt to analytically characterize the second law analysis and mixed convective rheology of the (Al2O3-Ag/H2O) hybrid nanofluid flow influenced by magnetic induction effects towards a stretching sheet. Viscous dissipation and internal heat generation effects are encountered in the analysis as well. The mathematical model of partial differential equations is fabricated by employing boundary-layer approximation. The transformed system of nonlinear ordinary differential equations is solved using the homotopy analysis method. The entropy generation number is formulated in terms of fluid friction, heat transfer and Joule heating. The effects of dimensionless parameters on flow variables and entropy generation number are examined using graphs and tables. Further, the convergence of HAM solutions is examined in terms of defined physical quantities up to 20th iterations, and confirmed. It is observed that large lambda 1 upgrades velocity, entropy generation and heat transfer rate, and drops the temperature. High values of delta enlarge velocity and temperature while reducing heat transport and entropy generation number. Viscous dissipation strongly influences an increase in flow and heat transfer rate caused by a no-slip condition on the sheet.

Automated summary

The study analyzes the mixed convective rheology and second law analysis of (Al2O3-Ag/H2O) hybrid nanofluid flow influenced by magnetic induction effects on a stretching sheet. Results show that a large value of lambda 1 can enhance velocity, entropy generation, and heat transfer rate, while reducing temperature; whereas a large value of delta increases velocity and temperature but decreases heat transport and entropy generation number.
