    Analysis of heat and mass transfer of an inclined magnetic field pressure-driven flow past a permeable plate
    (Applications and Applied Mathematics: An international Journal, 2017) Dada, M.S.; Salawu, S.O.
    The study considers heat and mass transfer of magnetohydrodynamics pressure-driven flow passed a stretching permeable surface in the presence of inclined uniform magnetic field. The equations governing the model are transformed by Lie’s group and solved using weighted residual method. The results obtained are compared with that of fourth order Runge-Kutta method that show the effects of Skin friction, Nusselt and Sherwood numbers on the flow. Finally, the influence of some important parameters on the flow are presented graphically and discussed.

    Analysis of unsteady viscous dissipative poiseuille fluid flow of two-step exothermic chemical reaction through a porous channel with convective cooling
    (Ain Shams Engineering Journal, 2019) Salawu, S.O.; Oladejo, N.K.
    In this study, the viscous dissipation of heat transfer of poiseuille fluid flow of two-step exothermic chemical reaction through a porous channel is investigated under different chemical kinetics. The flow is pressure-driven past fixed plates with heat generation. The upper wall surface is exposed to heat exchange with the temperature of the ambient aligning with the Newton’s law of cooling. The modeled coupled partial differential equations are non-dimensional and solved using stable and unconditional semi-implicit convergent finite difference method. The results are represented graphical and discussed accordingly for the velocity and temperature profiles showing the effect of some embodiment parameters entrenched in the system. From the results it was noticed that an increase in Frank-Kamenetskii parameters produces significant rises in the temperature distribution.

    Lie group analysis of Soret and Dufour effects on radiative inclined magnetic pressure-driven flow past a Darcy-forchheimer medium
    (Journal of the Serbian Society for Computational Mechanics, 2018) Salawu, S.O.; Dada, M.S.
    The study examines Soret and Dufour effects on steady convective heat and mass transfer of magnetohydrodynamic (MHD) pressure-driven flow in a Darcy-forchheimer porous medium with inclined uniform magnetic field and thermal radiation. The governing partial differential equations of the model are reduced to a system of coupled non-linear ordinary differential equations by applying a Lie group of transformations. The resulting coupled differential equations are solved using weighted residual method (WRM). The results obtained are presented graphically to illustrate the influence of various fluid parameters on the dimensionless velocity, pressure drop, temperature and concentration. Finally, the effects of Skin friction, Nusselt and Sherwood numbers results are presented and discussed accordingly.

    Radiative heat transfer of variable viscosity and thermal conductivity effects on inclined magnetic field with dissipation in a non–Darcy medium
    (Journal of the Nigerian Mathematical Society, Nigerian Mathematical Society., 2016) Salawu, S.O.; Dada, M.S.
    The study of thermal radiative heat transfer of an electrically conducting fluid over a continuously stretching sheet in the presence of a uniform inclined magnetic field with dissipation in a porous medium is investigated for power-law variation in the sheet temperature. The fluid viscosity and thermal conductivity are assumed to vary as a function of temperature. The governing partial differential equations of the model are reduced to a system of coupled non-linear ordinary differential equations by applying similarity variables and then solved numerically using shooting technique with fourth-order Runge-Kutta method. The results for Skin friction and Nusselt numbers are presented and discussed.

    Scaling group analysis of heat and mass transfer of magnetohydrodynamic pressure-driven flow past a permeable plate with inclined magnetic field
    (Journal of Nigerian Association of Mathematical Physics, 2016) Salawu, S.O.; Dada, M.S.
    This study investigates steady free convective heat and mass transfer of magnetohydrodynamic pressure-driven flow past a permeable plate with inclined uniform magnetic field. The governing partial differential equations of the model are reduced to a system of coupled non-linear ordinary differential equations by applying a scaling group of transformations. The coupled differential equations are solved numerically using the Weighted Residual Method. The results obtained were presented graphically to illustrate the influence of various parameters on the dimensionless velocity, temperature concentration and pressure drop. Finally, the effects of Skin friction Nusselt and Sherwood numbers which are of physical and engineering interest are also presented and discussed.
