Effect of magnetic field on Oldroyd-B type nanofluid flow over a permeable stretching surface

This article is conceded to explore the influence of magnetic flux on a two dimensional incompressible Oldroyd-B type nanofluid past a heat generating/absorbing permeable expanding surface. Guided by some appropriate similarity transformations, the fundamental PDEs are converted into a self similar system of coupled, non-linear ODEs. The findings are gained by taking the help of the Runge-Kutta Gill based Shooting practice. To visualize the influences of related parameters concerning the flow, on velocity, temperature and concentration distributions are represented through graphs. Numerical fallouts for the local Nusselt number and Sherwood number are charted for various parametric situations to offer interesting aspects of the investigation. In existence of magnetic flux the momentum boundary layer width declines rapidly with relaxation time and velocity slip whereas, the temperature boundary layer width enhances significantly with heat source, Brownian motion and thermophoresis parameters. The Nusselt number falls a lot with heat source, velocity slip and Brownian motion parameter but reverse result is notified for Sherwood number for the same. Also, the obtained numerical outcomes for particular cases are compared with those of the existing data in the open literature and, are found in excellent harmony.
