“…The aim here is to test our numerical results and compare them with published works results in the literature as limiting cases situations. Thus, we compare the present results with the available results in reference (Cortell, 2006;Ghadikolaei et al, 2018;Waqas et al, 2017;Megahed, 2013;Sadeghy et al, 2006;Mukhopadhyay, 2012). It is found that our results are in excellent agreement with those of Cortell (2006), Ghadikolaei et al (2018), Waqas et al (2017), Megahed (2013), Sadeghy et al (2006), and Mukhopadhyay (2012) as shown in Tables 2-5.…”

“…Because there are many different engineering issues and boundary conditions, extensive research has been conducted in this area, which is briefly summarized. Due to different boundary conditions and different geometric positions, Waqas et al (2017) discussed the stratification of the nonliquid flow with generating heat in a stretchable linear surface. Ghadikolaei et al (2018) analyzed the flow and heat of the second row liquid on a dilation sheet channel.…”

The objective of this study is to find the numerical solution for the MHD flow of heat transfer to the incompressible Oldroyd-B liquid on a stretching sheet channel. The partial differential equations governing this system are converted into ordinary differential equations using similarity conversion. The resulting nonlinear equations governing the flow problem are numerically solved by the successive line method (SLM). Numerical results are derived and presented in tables for some comparisons. These comparisons are important in demonstrating the high accuracy of SLM in solving the system of nonlinear differential equations. These solutions take into account the behavior of Newtonian and non-Newtonian fluids. It is reported that Deborah number in terms of relaxation time resists and slows down the motion of fluid particles at various time instants. Temperature profile increase by increasing Deborah number in terms of relaxation time. The graphical results of various non-Newtonian parameters such as coefficient of mixed convection, Hartman, Deborah, and Prandtl number on the flow, field, and analysis are also discussed. In addition, the current results were tested and compared to the published results available in a limited manner, and an excellent agreement was reached.

This study addresses the novel characteristics of infinite shear rate viscosity and entropy generation in magneto-mixed convective flow of cross-nanomaterial toward a stretched surface. Moreover, analysis of current research work has been prepared for Brownian moment and thermophoresis deposition. Radiation and viscous dissipation aspects are accounted. More specifically, roles of activation energy and Lorentz force on nanofluids transportation are examined. ODEs are acquired from PDEs via implementation of suitable transformations. Numerical algorithm is implemented to tackle the nonlinear system for numerical results. Discussion on rheological parameters involved in current research work is presented through graphs. Results demonstrate the significant rise in temperature and nanoparticles concentration with the intensification of Brownian moment aspects. More specially, we perceived that entropy rate is significantly affected by radiation parameter and Brinkman number. Intensification in entropy rate is observed for rising values of magnetic parameter, radiation parameter and Brinkman number.

“…Besthapu et al [15] reported double stratification and viscous dissipation effects in the mixed convective nanoliquid flow induced by an exponentially stretched surface. Characteristics of mixed convection in a doubly stratified Oldroyd-B nanofluid flow with heat generation were studied by Waqas et al [16]. Moreover, the convection heat problems associated with heat generation within a liquid are of great importance: for instance, there are various demands in energy associated problems.…”

Abstract. The mixed convective flow of an Eyring-Powell nanomaterial in a doubly stratified medium is addressed in this paper. The stretching surface has varying thickness. The nanofluid model given by Buongiorno is utilized in the formulation of energy and concentration expressions. Heat generation is also retained. Ordinary differential systems are obtained by utilizing the transformations procedure. Homotopy series solutions containing exponentially functions are developed. Significant characteristics of influential variables for velocity, temperature, nanoparticle concentration, skin friction coefficient and Nusselt and Sherwood numbers are reported through graphs and tables. It is found that stratification phenomenon leads to a decay in temperature and nanoparticle concentration.
