Abstract: This article gives brief summary about the boundary layer flow characteristics of magnetic generalized Newtonian fluid due to a paraboloid revolution under bioconvection and chemical reactive species. The nanofluid model utilized in this work includes the behavior of Brownian motion and thermophoresis. The differential equations can be determined by a similarity solution. The determined ordinary differential equations have been solved numerically by fifth order Runge–Kutta Fehlberg method-based shooting technique. The behavior of different physical controlling dimensionless parameters on the base flow velocity, temperature, concentration, skin friction heat and mass transfer rates are analyzed numerically and graphically. We observed that the velocity, temperature and concentration profile reduce for increasing values of Hartmann number, Weissenberg number, wall thickness, stretching index, bioconvection, Prandtl number, Lewis number and Brownian motions whilst behavior is noticed for power law index. Moreover, for increases the values of Brownian and thermophoresis parameter the temperature profile shown increasing behavior. Comparison has been with represents date and found that the results have good agreement.
