The main objective of current communication is to present a mathematical model and numerical simulation for momentum and heat transference characteristics of Maxwell nanofluid flow over a stretching sheet. Further, magnetic dipole, non-uniform heat source/sink, and chemical reaction effects are considered. By using well-known similarity transformation, formulated flow equations are modelled into OD equations. Numerical solutions of the governing flow equations are attained by utilizing the shooting method consolidated with the fourth-order Runge-Kutta with shooting system. Graphical results are deliberated and scrutinized for the consequence of different parameters on fluid characteristics. Results reveal that the temperature profile accelerates for diverse values of space dependent parameter, but it shows opposite behaviour for escalated integrity of temperature dependent parameter.

The present article aims to investigate the behaviour of Maxwell–Sutterby fluid past an inclined stretching sheet accompanied with variable thermal conductivity, exponential heat source/sink, magneto-hydrodynamics (MHD), and activation energy. By utilizing the compatible similarity transformations, the nondimensionless PDEs are converted into dimensionless ODEs and further these ODEs are tackled with the help of the bvp4c numerical technique. To check the legitimacy of upcoming results and reliability of the applied bvp4c numerical scheme, a comparison with existing literature and nonlinear shooting method is made. The numerical outcomes delivered here show that the temperature profile escalates due to an augmentation in the heat sink parameter and moreover mass fraction field escalates on account of an improvement in the activation energy parameter.

Three-dimensional magnetohydromagnetic slip flow of chemically reacting fluid over a variable thickness stretching sheet with space and temperature dependent heat source/sink was analysed numerically. Runge-Kutta and Newton’s methods are employed for solving the reduced ordinary differential equations with the help of similarity variables. Plots are demonstrated and examined for several parameters of concern. Also the effect of the same parameters on skin friction coefficient, heat and mass transfer rates are presented in tabular form. We found a good agreement of the present results by comparing with the published results. It is observed that space and temperature dependent heat source/sink parameters acts like controlling parameters of heat transfer. Slip effects reduce the development of concentration and thermal boundary layers.
