Abstract Most fluids used in industries possess a constant velocity acting with them. In spite of the fact that there have been a few studies conducted on the topic, the study of fluid flow at a constant velocity using nanofluids is still relatively unexplored. The novelty of this work is the analysis of the heat, and mass transfer of the nanofluid Al 2 O 3 –H 2 O along with a constant velocity in a rotating system with Soret–Dufour effects. This article aims to investigate the MHD nanofluid flow in a vertical plate with a porous medium taking into account viscous dissipation, Joule heating, and a non‐uniform heat source / sink. The investigation is subject to steady‐state incompressible flow through a vertical plate with a magnetic field and chemical reaction effects. Equations pertinent to nanofluid flow have been modeled as nonlinear partial differential equations. These equations are reformed as nondimensional ODEs utilizing suitable similarity transformations. Employing, the Runge–Kutta method the system of ODEs is solved. The physical impacts of the fluid parameters on velocity, temperature, and concentration are illustrated clearly using graphs. Tables are utilized to present the rate of heat, mass transfer as well as the skin‐friction coefficient. A limiting case of our work compared with the existing literature to validate our results. Our results show that when rotation parameter rises from 4 to 6, it decreases the heat transfer rate by 10.8% and mass transfer rate by 5.9%.
