“…This method is very productive in such a way that it does not require any of linearisation, discretization and the use of guess value or perturbation technique as discussed in [20]. Moreso, the literature is rich on the mADM and investigation are readily available in [30][31][32][33] including the convergence with size-able iteration in [34,35]. The comparison of the accuracy and its convergence were prepared in tables with respect to exact solution of fluid motion and discussed quantitatively the other thermophysical parameters present in the flow system.…”

This research work examines the influence of thermal radiation on the flow of a reactive hydromagnetic couple stress fluid flowing through a passable channel under the drive of heat source. The analytical expressions for the momentum and heat transfer are obtained to find the entropy generation rate using the modified Adomian decomposition method (mADM). The results are correlated with previously obtained results in the bid to ascertain and verity the efficacy of the mADM and mostly for end users to be able to predict the safe and unsafe situations. In addition to that, the effects of thermal radiation and other thermophysical parameters on fluid motion, energy transfer and rate of entropy generation are shown and discussed in tables and graphs.

“…Jha and Samaila 25 adopted convective boundary conditions in analyzing the implication of the thermal radiation past a flat plate. Hassan and Salawu 26 carried out an analysis of buoyancy-driven flow between the parallel vertical passage with convective boundary conditions. Aljoufi and Ebaid 27 explored the implication of using convective boundary conditions on flow physics past a stretching surface.…”

This piece of work explored the impact of nonlinear thermal radiation on natural convection flow in the vicinity of a constant moving vertical porous plate with suction/injection. The moving vertical porous plate is considered to be either move in the same direction with fluid in the free stream or move in the negative x-direction while the fluid move in the positive x-direction. The partial differential equations (PDEs) associated with the flow properties are simplified to ordinary differential equations (ODEs) using similarity variables. Then, the resulting ODEs and the boundary condition are translated into the IVP through the shooting method. Furthermore, the final IVP and the reduced boundary conditions are solved numerically through the Runge–Kutta method. The influence of the emerging dimensionless quantities is analyzed through tables and line graphs. The numerical results obtained revealed that with suction/injection, the shear stress could be enhanced by propagating the local convective heat transfer parameter Bix, nonlinear thermal radiation R and the local Grashof number Grx for the two cases of plate motion considered. The result also revealed that in the presence of suction/injection, the heat transfer rate decreases with Bix and Grx, whereas enhanced with R augment for the two plate motions considered. Furthermore, for a constant moving vertical porous plate and constant moving freestream velocity, the convective heat transfer parameter at any point x is proportional to the corresponding heat transfer coefficient related to hot fluid. The nonlinear thermal radiation enhances the velocity and temperature profiles.

“…They have noticed that the flow enhances with the constant pressure gradient and slows down with the magnetism. Hassan et al 35 have depicted the irreversibility analysis of reactive third‐grade fluid flow in a horizontal parallel microchannel under the influence of reactive heat generation and buoyancy force. Also, they have reported that the heat transfer enhances with the buoyancy force and heat source.…”

This paper analyses the generation of entropy in an electrically conducting third‐grade fluid through a vertical channel considering the variable thermal conductivity. Aspects of radiation, viscous dissipation, porous medium, Joule heating, convective boundary condition, and heat generation are studied. Nonlinear systems of ordinary differential equations are obtained via applying suitable dimensionless variables. After that, the system is solved with the aid of using the Runge–Kutta–Fehlberg method. The numerical solutions are used to characterize the irreversibility and irreversibility ratio. It is established that the entropy is enhanced with accelerating estimations of the third‐grade material parameter, Brinkman number, magnetism, Biot number, porous parameter, and the impact is decelerated with elevating values of the radiation. The rate of heat transfer is higher for the Brinkman number, and a similar impact on drag force is noticed for magnetic and Grashof numbers. All the parameters on flow, temperature, fluid irreversibility and irreversibility ratio are discussed through graphical illustration.
