Hybrid Nanofluid Flow Over a Moving Thin Needle with Thermal Radiation

Abstract

Hybrid nanofluid flow over a moving thin needle represents a crucial and practical physical configuration in various applications. Traditional fluids such as ethylene glycol, water, engine oil and lubricants exhibit low thermal conductivity, setting a fundamental limit on heat transfer. This study explores the effects of Soret and Dufour on hybrid nanofluid flow over a moving thin needle, incorporating thermal radiation, magnetohydrodynamics (MHD), the Casson model, porous medium, joule heating, heat sources or sinks, chemical reactions and Stefan blowing. The investigation also encompasses the influence of mass diffusion, contributing to a comprehensive understanding of heat and mass transport phenomena. Employing similarity transformations, the governing partial differential equations are converted into nonlinear ordinary differential equations. Subsequently, these transformed equations are semi-analytically solved using the homotopy analysis method (HAM) with Mathematica software. The study delves into the flow characteristics of heat and mass transfer for varied values of dimensionless parameters, including thermal radiation parameter, magnetic parameter, Casson parameter, Stefan blowing parameter, heat generation parameter, chemical reaction parameter, Soret and Dufour numbers, Eckert number and porosity parameter. Both visual representations and numerical data are furnished for the velocity profile, temperature profile, concentration profile, skin friction, Nusselt number and Sherwood number across a range of parameter values
