Development of convective heat transport in nanofluid flow of Oldroyd‐B model with magnetic dipole moment

The phenomenon of heat as well as mass transfer due to ferromagnetic flow of Oldroyd‐B nanofluid is addressed. The additional thermal source like heat source, thermal radiation, and activation energy features has been implemented to extend the dynamic of flow problem. The source of flow is moving stretching surface with magnetic dipole impact. The convective boundary conditions are implemented. The Boungrino nanofluid model is used to observe the thermophoresis and Brownian motion consequences. The mathematical modeling of problem in view of flow assumptions will be converted into the non‐dimensional form. The numerical shooting technique will be implemented for presenting the approximate simulations. After verifying the solution accuracy, the physical dynamic of problem with variation of parameter is presented. It is noticed that the velocity profile reduces due to ferrohydrodynamic interaction parameter. An enhanced thermal profile is observed due to relaxation time constant and ferrohydrodynamic interaction parameter. Furthermore, the concentration profile reduces for retardation time constant parameter.
