“…Prasad et al, [14] reviewed the influence of viscous dissipation on the fully developed combination of mixed convection and radiation effect in a vertical channel. Kalyan et al, [8] have analyzed the impact of a material characteristic on fully developed mixed convective micro-polar fluid flow in a vertical channel. Furthermore, chemical reaction improved flow reversal and allowed flow reversing for symmetrical wall temperatures [16].…”

An analysis of the impact of internal heat generation and other heat parameters on the temperature, velocity and rate of heat transfer of the liquid moving upward in a channel is studied. A fully developed non-Darcy flow using boundary conditions of the third kind with internal heat generation in a vertical channel is selected as the mathematical model. By utilising the similarity transformation, the governing equations are reduced to non-linear ordinary differential equations (ODEs). The converted ODEs are numerically solved and analysed using the fourth-order Runge-Kutta (RK4) method, incorporating a shooting technique with Newton’s method. The generated numerical algorithms are programmed in MATLAB for velocity, temperature and the local Nusselt number analysis. The numerical results of the flow and temperature variables are presented graphically. The impact of the parameters on the Nusselt number is also graphed to determine which of the three types of boundary conditions is the best for allowing heat transmission. The severity of flow reversal is increased under the Robin and Dirichlet conditions by enhancing the Darcy and Forchheimer numbers while decreasing the Brinkman and internal heat generation values. The temperature profiles improved with the increase in Brinkman numbers. Both Nusselt numbers remained constant for the Neumann boundary condition for all parameters except internal heat generation and local heat exponent. The Robin boundary condition is found to be the best facilitates heat transmission, since it delivers more pleasing and realistic results than the Dirichlet and Neumann conditions

“…In their publications, Kalyan et al, 10 Ishak et al, 11 and Sheikh et al 12 have examined the MHD micropolar fluid flow in a vertical channel. In his article, Kalyan 10 discovered that the material parameter is inversely related to fluid velocity and directly related to the microrotation velocity, while Sheikh et al 12 found in their study that the magnetic parameter reduces the fluid velocity as well as the magnitude of microrotation, and Ishak 11 found that dual solutions exist for the assisting flow. Sui et al 13 in their paper studied theoretically micropolar fluid flow by means of novel constitutive models in presence of heat transfer.…”

“…Numerous scholars, including Amin et al, Kartini et al, Ahmed et al, Ali et al, Mohammadein et al, Tassaddiq, and Gangadhar et al, [3][4][5][6][7][8][9] investigated the magnetohydrodynamic (MHD) boundary layer of flow in micropolar fluid with the result of viscous dissipation in these papers and reported some intriguing findings.

In this study, the researcher looks at the heat transmission of an incompressible magnetohydrodynamics micropolar fluid across a moving stretched surface in a Darcian permeable medium. The proper boundary conditions are used to facilitate the numerical solution (bvp4c) of the transformed governing equations. Graphical discussions have been made of the influence of the physical parameters on the velocity, angular velocity (microrotation), and temperature, and the distributions are accentuated on the plots via MATLAB. The study is validated by the previous work and it is found appropriate for investigation, where the absolute difference between the previous work and the present investigation by adopting the finite difference scheme is smaller than 1 0 − 5 $1 0^{\unicode{x02212} 5}$ which implies that the scheme is stable and convergent. The microrotation has a great impact on the micropolar fluid with the influences of buoyancy forces, source, and suction over the stretching surface in a Darcian regime. With a rise in the heat source parameter, both velocity and microrotational profiles lessen, but the opposite is true for temperature. Eringen number ( E r $E_{r}$ ) rises with the flow velocity, whereas temperature and microrotational profiles show the reverse relationship. The current study focused on particular applications in non‐Newtonian fluid mechanics, polymer flows in filtration systems and metallurgical procedures that included cooling unbroken strips or filaments via a static fluid.
