“…Das et al [6] and Makinde et al [18], investigated the Magnetohydrodynamics boundary layer flow over a vertical stretching/shrinking sheet in a nano-fluid. Das et al [7] investigated the effects of homogeneous-heterogeneous reactions on a stretching two dimensional mixed convection stagnation point boundary layer flow of an incompressible, viscous, electrically conducting, nonlinear, radiative heat transfer and chemically reacting copper-water nano fluid towards a linear stretching sheet using the spectral local linearization method. Fauzi et a.l [9] analyzed the effects of slip parameters A and B on a steady stagnation-point flow and heat transfer due to a shrinking sheet in a viscous and incompressible fluid by using shooting method.…”

This work investigates the mixed convection in a Magnetohydrodynamic (MHD) flow and heat transfer rate near a stagnation-point region over a nonlinear vertical stretching sheet. Using a similarity transformation, the governing equations are transformed into a system of ordinary differential equations which are solved numerically using the fourth order Runge-Kutta method with shooting technique. The influence of pertinent flow parameters on velocity, temperature, surface drag force and heat transfer rate are computed and analyzed. Graphical and tabular results are given to examine the nature of the problem. The heat transfer rate at the surface increases with the mixed convection.

“…Recently, Sreelakshmi and Sarojamma analyzed the heat transfer in the non‐orthogonal stagnation point flow of upper convected Maxwell fluid with nonlinear thermal radiation. The stagnation point flow of copper–water nanofluid with nonlinear thermal radiation and chemical reaction is studied by Das et al A theoretical investigation has been carried out by Awais et al to analyze the motion of polymeric fluids with nonlinear thermal radiation and nanoparticles. A numerical study has been performed by Kumar et al to discuss the impacts of double diffusion and nonlinear thermal radiation on the flow of electrically conducting viscoelastic fluid.…”

A numerical study is performed to discuss the heat and mass transfer on oblique stagnation point flow over a lubricated surface with nonlinear thermal radiation and higher-order chemical reactions. The problem is formulated using basic conservation laws of mass, momentum, energy, and mass concentration in terms of partial differential equations along with nonlinear boundary conditions. These governing equations are transformed into ordinary differential equations by means of similarity transformations. The system of resulting ordinary differential equations are solved numerically by an implicit finite difference scheme known as the Keller-box method. The quantities elaborated in the problem, such as velocity, temperature, skin friction, and local Nusselt and Sherwood numbers are analyzed for several values of involved parameters. The obtained results are presented through various graphs and tabular data and showed a good agreement with the existing results in the literature, which are the subcases of the present work. The heat transfer rate enhances with nonlinear thermal radiation and mass transfer rate decreases with increasing the order of chemical reaction.

“…Nandkeolyar et al [23] examined the combined effects of MHD and heat generation of a nanofluid past a stretching sheet with homogeneous-heterogeneous reactions and obtained the numerical solutions of two types of nanofluid including copper and gold nanoparticles. The mix convective flow near a stagnation-point of a nanofluid towards a stretching sheet in the presence of thermal radiation and homogeneous-heterogeneous reactions was investigated by Das et al [24]. Recently, Hayat et al [25] studied the boundary-layer flow of a carbon nanotubes near a stagnation point towards a porous stretching cylinder with homogeneous-heterogeneous reactions.…”

This research addresses the axi-symmetric flow of a Cu-water nanofluid past a porous shrinking cylinder in the presence of homogeneous-heterogeneous reactions. Using a similarity transformation, the basic PDE's are converted into ODE's. The transformed equations are solved using bvp4c numerically from MATLAB for several values of the physical parameters. The physical impact of governing parameters on the velocity profile, temperature profile, concentration profile as well as the skin friction coefficient, (0) f ′′ , and the heat transfer rate, (0) θ ′ − , are discussed carefully. The results indicate that the multiple solutions only exist when a certain value of suction is implemented through the permeable cylinder. Further, the curvature parameter, γ , accelerates the boundary-layer separation.
