Analysis of fluid flows having MHD and thermal radiation impacts over a stretchable cylindrical pipe under the influence of suction and injection

Abstract

Engineers and scientists have recently shown considerable interest in studying the f luid flow and heat transfer around elongating cylinders either for Newtonian or non Newtonian fluids. The interest in this topic originates from its widespread application in several industrial sectors, such as drawing of wire, cooling of metallic sheets, spinning of metal, etc. Similarly, Magnetohydrodynamics is the knowledge of the interaction between fluids that carry electricity and magnetic fields. Magnetic fields have an impact on a broad range of natural and man-made flows. Since the MHD boundary layer f low has many applications in different mechanical and chemical sectors, it has been researched extensively over a surface that stretches either linearly or nonlinearly. In industry, magnetic fields are commonly applied to heat, lift, stir, and pump liquid metals. Moreover, in recent years, the study of combined heat and mass transfer mechanisms involving nanoparticles has drawn significant interest from researchers, largely due to its wide range of applications in engineering and biomedicine, such as cooling infinite metallic plates, cancer therapy, and various industrial processes. Traditional fluids including glycol, motor oil, water, and air mixes often have limited heat conductivity. This is made better by incorporating solid particles into the fluids to create "nanofluid". Last but not least, The research of suction and injection across a stretched surface is crucial in fluid dynamics, due to its vast variety of industrial and technical applications. These processes are critical for improving systems such as polymer extrusion, aerodynamic heating, and chemical processing. Suction and injection considerably alter boundary layer flow, consequently affecting heat and mass transfer rates, which are crucial for maintaining optimum operating conditions and enhancing system efficiency
