Aspects of active-passive controls of nanoparticles of chemically reactive and radiative nanofluid flow past a frequently moving thin needle with thermal and velocity slip: A numerical framework

This communication unfolds the flow features and distribution of mass, heat of a steady MHD nanofluidic stream over an axially moved thin needle with passive and active controls of tiny particles. A linear sort of heat radiation with magnetic influence and a higher-order chemical reaction are addressed in this study. The investigation has been enriched by the consideration of thermophoretic forces with the Brownian movement of fluid. The statement of the problem is formed on the basis of Buongiorno's model, which introduced the existence of thermal & velocity slips. A suitable set of conversions was utilized to transfigure the foremost equations into nondimensional ordinary ones. Due to the extreme nonlinearity of this problem, we avoid the analytical scheme of solution. Hence, we have implemented the RK4 procedure in shooting approach through the algebra software MAPLE 2017, to solve it in a numerical manner. Numerous graphical diagrams and tables are buildups to discuss our attained impacts. Also, it is ensured the validation of these results with the study which was published earlier. Investigation depicts that the order of chemical reaction intensifies fluid density for active control, while the reverse is recorded in the passive strategy. Velocity slip amplifies the drag friction but reduces the transportation of heat. In the active control system, advanced chemical reaction offers more transmission of heat, but the opposite happens in another control.
