This study used a novel Casson model to investigate the flow of hybrid Al2O3-Cu/ethylene glycol nanofluid over a moving thin needle under MHD, Dufour-Soret effects, and thermal radiation. The governing partial differential equations were transformed into ordinary differential equations using appropriate transformations, and these equations were solved analytically using HAM. The study analyzed the effects of various parameters on velocity, temperature, and concentration profiles, and also discussed the impacts of the Casson parameter and the inclusion of nanoparticles on skin friction coefficient and heat transfer rate. The article also entangled local skin friction, a local Nusselt number, and a local Sherwood number for multiple parameters.
The current study used a novel Casson model to investigate hybrid Al2O3-Cu/Ethylene glycol nanofluid flow over a moving thin needle under MHD, Dufour-Soret effects, and thermal radiation. By utilizing the appropriate transformations, the governing partial differential equations are transformed into ordinary differential equations. The transformed ordinary differential equations are solved analytically using HAM. Furthermore, we discuss velocity profiles, temperature profiles, and concentration profiles for various values of governing parameters. Skin friction coefficient increases by upto 45% as the Casson parameter raised upto 20%, and the heat transfer rate also increases with the inclusion of nanoparticles. Additionally, local skin friction, a local Nusselt number, and a local Sherwood number for many parameters are entangled in this article.
