“…Datta and Mishra (1982) presented the boundary layer flow of a dusty fluid over a semi-infinite flat plate along with the drag force. Due to these applications, a number of theoretical and experimental studies have been carried out by numerous researchers on dusty fluid (see (Palani and Ganesan 2007;Ramesh et al 2017;Kumar et al 2017aKumar et al , 2017dMakinde et al 2017)). …”

Background: This paper explores the impact of thermal radiation on boundary layer flow of dusty hyperbolic tangent fluid over a stretching sheet in the presence of magnetic field. The flow is generated by the action of two equal and opposite. A uniform magnetic field is imposed along the y-axis and the sheet being stretched with the velocity along the x-axis. The number density is assumed to be constant and volume fraction of dust particles is neglected. The fluid and dust particles motions are coupled only through drag and heat transfer between them. Methods: The method of solution involves similarity transformation which reduces the partial differential equations into a non-linear ordinary differential equation. These non-linear ordinary differential equations have been solved by applying Runge-Kutta-Fehlberg forth-fifth order method (RKF45 Method) with help of shooting technique. Results: The velocity and temperature profile for each fluid and dust phase are aforethought to research the influence of assorted flow dominant parameters. The numerical values for skin friction coefficient and Nusselt number are maintained in Tables 3 and 4. The numerical results of a present investigation are compared with previous published results and located to be sensible agreement as shown in Tables 1 and 2. Conclusion: It is scrutinized that, the temperature profile and corresponding boundary layer thickness was depressed by uplifting the Prandtl number. Further, an increase in the thermal boundary layer thickness and decrease in momentum boundary layer thickness was observed for the increasing values of the magnetic parameter.

“…Initially, Saffman [32] described the fluid-particle system and obtained the equation of motion for fluid carrying the dust particles. The heat transfer effects on dusty gas flow past a semiinfinite isothermal inclined plate was analyzed by Palani and Ganesan [27]. Nandkeolyar et al [23] considered the natural convection boundary layer flow of a viscous, incompressible, and electrically conducting dusty fluid past an impulsively moving vertical plate with ramped temperature in the presence of thermal radiation and transverse magnetic field.…”

Abstract. 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.

The current investigation deals with melting heat transport in hyperbolic tangent fluid past a stretching sheet with fluid particle suspension and thermal radiation. Numerical solution is obtained via shooting technique after the applying of similarity variables to the governing partial equations. The effects of key parameters like magnetic parameter, fluid particle interaction parameter, Eckert number, Prandtl number, Weissenberg number and melting parameter are analyzed and discussed in detail with help of graphs and tables. Finally, the numerical values of the friction co-efficient and local Nusselt number are tabulated. Checked our results with existing work found excellent agreement. Results reveals that in the presence of melting parameter, the higher values of W e and n depreciates the rate of heat transfer.
