Abstract
Abstract This study investigates the consequences of steady and unsteady nanofluid flow over a bidirectional stretching sheet. Herein, the magnetic field is working in the normal direction. The Brownian motion together with thermophoresis is taken into consideration. Moreover, the chemical reaction within the nanoingredients also occupies a novel corner in this study. The leading equations of the considered model are transferred to nonlinear ordinary differential equations (ODEs) by an appropriate similarity transformation. The differential transformation method is used to solve the set of ODEs. We have used MAPLE‐17 software to solve this with the desired accuracy rate. Results are portrayed with graphs and tables. The corresponding physical consignments such as the Nusselt number, skin friction, and the Sherwood number are exhibited. Excellent improvement in heat and mass transport is observed, which can be visualized through tables. Outcomes reveal that both the temperature and x ‐direction velocity are reduced for the stretching parameter. Heat transport escalates for stretching factor, but higher outcomes are marked for the unsteady flow as compared with the steady flow. The mass transfer also increases for the chemical reaction factor, but the rate of increment is higher for the unsteady flow.
