“…When the relation between heat transfer and local temperature is directly proportional, we call this statement Newtonian heating; it may also be referred to as the heat flowing between a surface and fluid inside it or outside the surface, which will occur as a result of colliding objects. Merkin [27] discussed the heat transfer phenomena in a list of four: firstly Newtonian heating, secondly the boundary condition of heat transfer rate, thirdly the heat flux for the constant surface, and the last one is for surface temperature. ere are a lot of researcher works on the study of Newtonian heating [25,[28][29][30][31].…”

In this article, MHD flow of silver/water nanofluid past a stretched cylinder under the impact of thermal radiation with chemical reaction and slip condition is studied. The impact of Soret and Dufour effect is also analyzed during this flow. The uniqueness of the given problem is enlarged with the insertion of variable magnetic field, free stream velocity, thermal slip condition, and nonlinear thermal radiation. The PDEs are converted to ODEs by using suitable similarity transformation. The nonlinear system of ODEs is solved by applying convergent homotopy analysis method (HAM). The velocity, temperature, and concentration profiles for the free stream and at the plate are discussed through graphs and numerical tables. It is found that velocity field reduces, while the temperature profile rises for the increasing values of magnetic parameter. It is examined that effects of curvature on frication factor are increasing. Furthermore, temperature profile increases for greater Brownian motion and thermophoresis parameters. Transfer of heat enhances decreasing the radius of the cylinder also with heat generation parameter. The skin friction can be reduced by enhancing free stream and wall stretching velocities ratio. Velocity profile of the flow can be controlled by enhancing velocity slip and magnetic field.

This research studies the behaviour of hybrid nanofluid on mixed convection flow over a stretching sheet by considering the effect of non-uniform heat source/sink. The chosen base fluid is water with two different nanoparticles which are copper and aluminium oxide. The governing partial differential equations are reduced into ordinary differential equations using a similarity transformation technique. The resulting governing system then solved numerically using Keller-box method. The influence of space- and temperature-dependents of non-uniform heat source and sink parameters as well as the unsteadiness parameter is presented graphically. The current study shows that, the space- and temperature dependents of non-uniform heat source and sink significantly raises the fluid’s temperature. Comparative study also shows that hybrid nanofluid has higher temperature and heat transfer coefficient than single nanofluid and conventional fluid. It can also be concluded that, the enhancement of heat transfer rate can be achieved by reducing the parameter of space- and temperature dependents of non-uniform heat source and sink.

The present exploration aims to deliberate silver-water nanofluid flow with homogeneous–heterogeneous reactions and magnetic field impacts past a nonlinear stretched cylinder. The novelty of the presented work is enhanced with the addition of Newtonian heating, heat generation/absorption, viscous dissipation, nonlinear thermal radiation and joule heating effects. The numerical solution is established via Shooting technique for the system of ordinary differential equations with high nonlinearity. The influences of miscellaneous parameters including nanoparticles volume fraction 0.0 ≤ ϕ ≤ 0.3 , magnetic parameter 1.0 ≤ Μ ≤ 4.0 , nonlinearity exponent 1.0 ≤ n ≤ 5.0 , curvature parameter 0.0 ≤ γ ≤ 0.4 , conjugate parameter 0.4 ≤ λ ≤ 0.7 , heat generation/absorption parameter ( 0.2 ≤ E c ≤ 0.8 ) , radiation parameter 0.7 ≤ K * ≤ 1.0 , Eckert number ( 0.1 ≤ E c ≤ 0.7 ) , strength of homogeneous reaction 0.1 ≤ κ 1 ≤ 1.8 , strength of heterogeneous reaction 0.1 ≤ κ 2 ≤ 1.8 and Schmidt number ( 3.0 ≤ S c ≤ 4.5 ) on axial velocity, temperature profile, local Nusselt number, and skin friction coefficient are discussed via graphical illustrations and numerically erected tabulated values. It is examined that the velocity field diminishes while the temperature profile enhances for mounting values of the magnetic parameter. An excellent concurrence is achieved when our obtained numerical calculations are compared with an already published paper in limiting case; hence dependable results are being presented.
