“…Before applying the finite difference method (FDM) used by Ashraf et al [18] and many other, for the proposed dimensionless model presented in equations ( 8)-( 11) along with boundary conditions (12), it is first transformed into a convenient form by applying primitive variable formulation (PVF) to make the algorithm smooth. en, the dimensionless transformed model is discretized by using a finite difference scheme.…”

In the current study, the physical behavior of the boundary layer flows along a curved surface owing exothermic catalytic chemical reaction, and the magnetic field is investigated. The mathematical model comprised of a part of momentum, energy, and mass equations, which are solved using a finite difference method along with primitive variable formulation. Numerical solutions, using the method of quantitative differentiation, are made with the appropriate choice of dimensionless parameters. Analysis of the results obtained shows that the field temperature and flow of fluids are strongly influenced by the combined effects of catalytic chemical reactions and the magnetic field. The effects of skin friction, heat transfer, mass transfer, mass concentration, and temperature distribution along the curved surface are illustrated in the plots and in the form of tables. By setting the controlling parameters at the boundaries, the boundary conditions at the surface and away from the surface are determined in each graph. With a larger range of body shape parameter n, skin friction and heat transfer are improved, but mass transfer is reduced. Due to the increasing values of the exothermic parameter, the fluid velocity and mass concentration are decreased gradually and the temperature distribution is increased dramatically.

“…In recent years and decades, there has been a great deal of heat transfer and fluid flow research in horizontal or vertical channel involving free, forced, or combined convection, works by Quntiere and Muller [19], Pop et al, [20] as well as Jayabalan et al, [21]. When natural convection and forced convection mechanisms work together to transfer heat, this is referred to as combined forced convection and natural convection.…”

Numerical simulations of flow and heat transfer in an unsteady oscillatory fully developed combined convection are conducted. The temperature on the right wall varies with sinusoidal rhythm over time within a locked mean temperature, whereas the temperature on the left wall remains constant. Both walls are also considered to be stationary. A numerical solution for the momentum and energy equations obtained using the Runga- Kutta method is used to analyze the effect of periodic oscillation on the velocity and temperature configurations, as well as the progression of heat generations. The combined convection process of heat transfer and its flow pattern in a vertical channel is important in many applications, including environmental, industrial, and engineering. This study is prompted by a problem with the heat transfer process, which is difficult, expensive, and time-consuming. The purpose of this study is to develop a mathematical model, find a numerical solution, and conduct parametric studies on the double-diffusive fully developed vertical channel with unsteady oscillatory flow, as well as to investigate the effect of various parameters on the velocity and temperature profiles. The effect of different dimensional parameters is tested and the flow reversal phenomenon is discussed. The dimensional equations are transformed into non-dimensional equations using the similarity technique. Then, the built-in program dsolve in Maple is used to numerically solve the boundary value problem (BVP). A validation study is conducted on a previously reported problem to confirm the validity of the present calculation. The flow and temperature numerical findings are represented visually. It is found that a large development of flow is caused by the plate temperature oscillation with high amplitude, therefore, the nature of the flow differs from the non-oscillating case.

Heat enhanced by an exothermic reaction on a fully developed MHD mixed convection flow in a vertical channel with first order chemical reaction is analyzed by Jayabalan et al, [6].

An inspection is implemented to study MHD slip flow of viscous reactive fluid in a convectively heated porous vertical channel. The ordinary differential equation governing the flow field is solved by a semi-analytical method (perturbation series method) where suction/injection is used as a fluid controller in the channel. The results are presented graphically and discussed quantitatively with respect to various parameter embedded in the problem. It is observed that for both suction/injection, increase in Magnetic field parameter, decrease the velocity flow and skin friction.
