Intensification of Heat Transport due to Solar Radiation in the Flow of Boger Nanofluid Considering Nanoparticle Shape Effect.

The shape factors of the nanoparticles play a vital role in defining the system's thermal conductivity and heat transfer rates. Thermal radiation is another significant factor in some circumstances, mainly when a more realistic representation of the radiative heat transport is required. In view of this, this study explores the effects of cylinder, platelet and brick-shaped nanoparticles on a magneto-Boger nanoliquid flow over a stretching sheet with nonlinear, quadratic, and linear TR effects. The governing partial differential equations are converted into ordinary differential equations with the aid of similarity variables. The findings of the current investigation are attained using the Runge–Kutta–Fehlberg fourth–fifth order technique. The impact of numerous parameters on the development of flow patterns is shown through graphs. Indeed, the highest dynamic viscosity appears to be present in the nanofluid containing platelet-shaped nanoparticles, whereas brick-shaped nanoparticles exhibit the strongest thermal conductivity. Among the three radiation types, nonlinear TR exhibits the most heat transmission, followed by quadratic and linear TR. This study's findings are significant in the planning and development of nuclear reactors, solar thermal collectors, electronic gadgets, combustion systems, and high-efficiency cooling systems. The shape effect of nanoparticles like bricks, platelets, and cylinders is considered. Examining these diverse nanoparticle forms can modify nanofluids for specific uses, enhancing their stability and thermal performance in a range of cooling and heat transfer systems. This motivated us to study the MHD stream and thermal behaviour of a Boger nanofluid, which is affected by linear, nonlinear, and quadratic thermal radiation. [ABSTRACT FROM AUTHOR]
