Radiation Effects on Inclined Magnetohydrodynamics Mixed Convection Boundary Layer Flow of Hybrid Nanofluids over a Moving and Static Wedge

Abstract

Nowadays, hybrid nanofluids play an important role in heat transfer systems. They are a good alternative to increase the efficiency of heat transfer and save the energy. Thermal radiation and mixed convection flow of hybrid nanofluids past a permeable moving and stationary wedge were studied in this research. This research uses water as a base fluid to investigate the effects of silver (Ag) and magnesium oxide (MgO) nanoparticles. Similarity transformation techniques are used to convert the partial differential equations of hybrid nanofluids to ordinary differential equations, which is then solved numerically by applying the implicit finite difference Keller box method. The results of the research are illustrated graphically to show the behavior of velocity and temperature profiles, as well as skin friction and Nusselt number. Increasing the parameters of the aligned magnetic field, magnetic field interaction, mixed convection, and wedge angle parameter results in higher velocity profiles but lower temperature profiles. As the radiation parameter and the nanoparticle volume fraction increase, the temperature rises and the velocity decreases. With the exception of the radiation parameter, the skin friction and Nusselt number increase as the alignment angle of the magnetic field, the interaction of the magnetic field, the mixed convection, the wedge angle parameter, and the volume fraction of nanoparticle Ag and MgO rise. As a result of these findings, the velocity profiles and Nusselt numbers of moving wedges are higher, but the temperature profiles and skin friction are lower than those of stationary and moving against flow wedges. In addition, a comparison with previously published research is presented, with excellent agreement discovered. The results of this research will contribute to the field of knowledge in mathematics by bringing additional information for mathematician interested in future research on hybrid nanofluids.

Aligned Magnetohydrodynamics and Thermal Radiation Effects on Ternary Hybrid Nanofluids Over Vertical Plate with Nanoparticles Shape Containing Gyrotactic Microorganisms

“…Several researchers, as referenced in [38][39][40], have investigated the effect of radiation on MHD under different conditions. They found that radiation tends reduce the velocity while increase the temperature.…”

The Newtonian heating effect on MHD free convective boundary layer flow of magnetic nanofluids past a moving inclined plate

“…The fluid flow and heat transfer in the presence of the magnetic field by Noranuar et al (2021) found that the temperature increases while the nanofluid velocity reduces with a higher magnetic strength. In the year 2022, the study of the nanofluids with the presence of MHD effect by Rosaidi et al (2022), Nayan et al (2022), Bosli et al (2022), andIshak et al (2022) found that with the effect of the magnetic field increase the heat transfer as well as the velocity of the study. Study on the MHD effect was discovered in different situations by some researchers such as Ilias (2018), Ahmad et al (2019), Khashi'ie et al (2019), and Soid et al (2022.…”

An Experimental Study of the Transfer of Heat in Nanofluid of a Tiny-Channel using Several Innovative Arrangement Designs

“…The Nusselt number of the nanofluid consisting of Al2O3 and H2O exhibits the highest enhancement in concentration at 0.01% when the Reynolds number (Re) is approximately 5200, resulting in a maximum rise of 47.5%. The observed augmentation in the friction factor of the nanofluid amounts to 15.1% [25][26][27][28][29]. The findings of earlier experiments were compared to determine the effective heat transfer of lowconcentration nanofluids under low flow resistance, as indicated by the Nu and f values.…”
