The heat transfer in nanofluids plays a major role in solar energy, nuclear reactors, aerodynamics, etc. By keeping this in view, in this study, we investigated the flow and heat transfer nature of liquid film flow of ethylene glycol (EG)-Cu nanofluid in the presence of non-uniform heat source/sink. We considered the Jeffrey fluid model to investigate the flow and heat transfer behavior. The governing equations are transformed as ordinary differential equations with the aid of similarity variables. Numerical results are carried out by employing bvp5c Matlab package. The influence of pertinent parameters on velocity and temperature profiles along with the reduced Nusselt number is discussed with the help of graphs and tabular results. It is observed that the rising value of the non-uniform heat source/sink parameter acts like heat generators and regulates the thermal field. Rising the film thickness enhances the heat transfer rate.

This paper considers the problem of steady, boundary layer flow and heat transfer of dusty nanofluid over a stretching surface in the presence of non-uniform heat source/sink and nonlinear thermal radiation with Biot number effect. The base fluid (water) is considered with silver (Ag) nanoparticles along with suspended dust particles. The governing equations in partial form are reduced to a system of non-linear ordinary differential equations using suitable similarity transformations. An effective Runge–Kutta–Fehlberg fourth-fifth order method along with shooting technique is used for the solution. The effects of flow parameters such as nanofluid interaction parameter, magnetic parameter, solid volume fraction parameter, Prandtl number, heat source/sink parameters, radiation parameter, temperature ratio parameter and Biot number on the flow field and heat-transfer characteristics were obtained and are tabulated. Useful discussions were carried out with the help of plotted graphs and tables. Under the limiting cases, comparison with the existing results was made and found to be in good agreement.

PurposeThe purpose of this paper is to examine the influence of magnetic field on Williamson nanofluid embedded in a porous medium in the presence of non-uniform heat source/sink, chemical reaction and thermal radiation effects.Design/methodology/approachThe governing physical problem is presented using the traditional Navier–Stokes theory. Consequential system of equations is transformed into a set of non-linear ordinary differential equations by means of scaling group of transformation, which are solved using the Runge–Kutta–Fehlberg method.FindingsThe working fluid is examined for several sundry parameters graphically and in a tabular form. It is noticed that with an increase in Eckert number, there is an increase in velocity and temperature along with a decrease in shear stress and heat transfer rate.Originality/valueA good agreement of the present results has been observed by comparing with the existing literature results.
