Flow of couple stress nanofluid due to stretching surface with applications of induced magnetic field and variable thermal conductivity

Abstract

Owing to current evolution in nanotechnology, the idea of nanomaterials has been developed to improve the heat transfer phenomena. In order to obtain diverse significance of nanomaterials in engineering systems, applications of different thermal sources are contributed. The aim of current analysis is to presents the induction of induced magnetic force for couple stress nanofluid due to moving stretched surface. For prediction of heat and mass phenomenon, variable role of thermal conductivity and mass diffusivity of nanofluid is assumed. Furthermore, the heat transfer rate is further influenced by nonlinear radiated phenomenon. The convective boundary constraints are taken to enhance the thermal pattern. The problem modeled via governing equations is numerically solved with shooting method. Simulations are captured with physical explanations. It is claimed that the interaction of magnetic number leads to decrement in the velocity. The enhancement in heat and mass transfer have been exhibited due to magnetic number. Current results attribute applications in plasma physics, thermal systems and electromagnetism. Moreover, summarize observations preserve biomedical applications like magnetic resonance imaging (MRI).
