Exploration of motion of methanol experiencing alumina and silica nanoparticles with emphasis on multiple solutions

Abstract

There is an increasing industrial demand to improve the thermal characteristics of fluids as they flow over stretching/shrinking and rotating surfaces. Heat transfer liquids, thermal exchangers, and coolants in electronics are examples of applicable applications. The thermal transport characteristics of hybrid nanofluids are improved by the inclusion of composite nanoparticles. Because the hybrid nanofluids can improve thermal conductivity compared to traditional fluids. However, several investigations are still needed to fully comprehend its features. Hence, this study investigates the fluid flow and thermal transport properties of thermally radiated hybrid alumina-silica/methanol nanofluid in a three-dimensional domain through a permeable porous shrinking surface. The hybrid nanofluid flow model of PDEs is transformed into ODEs by using similarity conversion, which is then numerically solved in MATLAB using the bvp4c solver. The characteristics of hybrid nanofluid velocity, thermal distribution, friction drag, and heat transport rate are graphically depicted for various physical flow parameters. The outcomes reveal that the range of first and second solutions can be augmented by increasing nanoparticle volume percentage. Furthermore, the results suggest that increasing the suction parameter can improve the effective heat transfer performance of the hybrid nanofluid whereas thermal radiation and heat source/sink parameters have no effect on delaying the boundary layer separation.
