Numerical and regression analysis of horizontal magnetic field in slippery nanofluid flow with Arrhenius activation energy

Abstract

The significance of magnetic field in the fluid flow models is important in order to stabilize the flow stream. The present work explores the horizontal magnetic field influences in steady-state laminar swirl Newtonian nanomaterial fluid flow triggered by disk rotation. To categorize the thermal performance, a well-established theory of nanofluid (Buongiorno model) is implemented in flow phenomenon. Thermal radiative term is demonstrated in the energy transportation equation. The impact of chemical species is investigated by the expression of AAE (Arrhenius activation energy). The flow model is normalized in accordance with von Kármán similarity transformations. The resulting normalized system of equations is converted to a system consisting of first order differential equations and then is solved by Runge-Kutta-Fehlberg (RKF-45) built-in method. The physical results are discussed graphically on velocity, temperature, and concentration streams. Shear stresses, local Nusselt and Sherwood numbers are calculated at the surface of the rotating disk. In addition, the regression process is utilized to address the parameters impacts on the variables. The stabilizing impact of magnetic field along radial direction is noticed by means of direction angle close to 00 and 900. Velocity profiles in radial direction are enhanced by the velocity slip parameter. Concentration filed is increased through activation energy. The inclination angle has a weak impact on heat transfer rate. Finally, a comparison is established with the published literature in limiting scenario.
