Active and passive control of nanoparticles in ferromagnetic Jeffrey fluid flow
The rheology of non‐Newtonian liquids has fascinated several researchers due to their wide‐ranging applications in manufacturing and engineering sectors like plastic processing, the mining industry, and lubrication. Also, the features of ferromagnetic non‐Newtonian fluids make it supportive for extensive usage in loudspeakers, magnetic resonance imaging, computer hard drives, directing of magnetic drugs, and magnetic hyperthermia. Owing to such potential applications, the current study is concerned with the heat and mass transfer analysis in a ferromagnetic Jeffrey liquid flow over a stretching sheet. In the flow problem, Brownian moment, magnetic dipole, and thermophoresis features are used. The active and passive control of nanomaterials is also considered in the modeling. Using appropriate similarity transformations, the modeling equations are converted to ordinary differential equations, then these equations are solved using the Runge–Kutta process and the shooting approach. The numerical and graphical solutions for the thermal profile, concentration profile, skin friction, rate of heat, and mass transfer characteristics are obtained. The significant results of the current study are that the thermal profile is strongly stimulated and increases faster for active control case than passive control case for augmented values of thermophoresis parameter. The heat transfer is strongly stimulated and decreases faster for passive control case than active control case for growing values of Deborah number. The mass transfer rate decreases faster for the active control case for increasing values of Schmidt number.
