Impact of viscous dissipation and radiation on MHD free convective mass transfer of an incompressible, viscous fluid flow through a stretching surface is examined. By applying similarity variables, the governing non-linear PDE's are converted into nonlinear ODEs. Keller-Box approach gets numerical solutions to these equations. The effect of non-dimensional variables is studied and graphically illustrated on velocity, temperature, and concentration. It is observed that the growth in the chemical reaction parameter, Schmidt number, Eckert number, Radiation, and Magnetic parameter (M) surges the temperature profiles, while the increase in the chemical reaction parameter, Magnetic parameter (M), and Schmidt number diminishes the Velocity profile. The friction factor, Nusselt, and Sherwood numbers are also investigated and arranged for different values of chemical reaction, magnetic field, and Schmidt number in tabular form. The findings of this study are very well-acknowledged with current research.
The current study aims to investigate the influence of porosity in the presence of radiation, and viscous dissipation on two‐dimensional unsteady magnetohydrodynamics mixed convection heat and mass transfer flow at the stagnation point. The governing time‐dependent nonlinear partial differential equations are converted into a nonlinear ordinary differential equation by utilizing similarity transformations. The transformed equations are solved by employing the bvp4c technique, a well‐known numerical approach. The influence of nondimensional factors on fluid velocity, temperature, and species concentration profiles is explored and graphically represented. For varied values of the Prandtl number, magnetic field, and Schmidt number, the friction factor, Nusselt, and Sherwood numbers are also explored and provided in tabular format. As increasing the porosity parameter, the temperature profile, concentration profile is growing, and velocity profile diminishes. The conclusions of this study are widely accepted by the scientific community.
The purpose of this study is to analyze the impact of velocity slip, chemical reaction, and suction/injection on two-dimensional mass transfer effects on unsteady MHD flow over a stretching surface in the presence of thermal radiation and viscous dissipation. The governing time-dependent nonlinear partial differential equations are transformed into nonlinear ordinary differential equations by using similarity transformations. The converted equations are solved using the numerical technique with the help of Keller-Box method. The effect of nondimensional variables is studied and graphically illustrated on velocity, temperature, concentration, friction factor, Nusselt number, and Sherwood number. Concentration and temperature profiles are enhanced and the contrasting pattern for velocity profiles as increasing the velocity slip and magnetic parameter. The concentration profile is diminished as the Schmidt number (Sc) and chemical reaction (C r ) increase. The concentration, velocity, and temperature profiles display a reversal pattern, as the suction and unsteady parameter (A)
