This study investigates the flow, heat and mass transport attributes of the three-dimensional motion of a magnetohydrodynamic rotating fluid. The vital interest in this article is to investigate the effect of cross diffusion, thermophoresis and Brownian motion in the presence of rotating flow past a stretching surface. The partial differential equations explaining the flow situation have been converted into dimensionless ordinary differential equations with the help of suitable transformations. The solution of the problem is achieved by taking the advantage of the shooting and Runge-Kutta numerical algorithms. From the solution, it is perceived that the flow is affected by sundry physical quantities like the Soret and Dufour effects, thermophoresis and the Brownian moment. The impact of these parameters on the momentum, energy and mass transport is discussed with graphical and tabular results. From the results we infer that the rotation decreases the flow field and encourages the thermal and concentration fields. © 2017 The Physical Society of the Republic of China (Taiwan)
