Finite di®erence scheme of time-dependent MHD viscous °uid °ow

In this paper, we investigate time-dependent viscous °uid °ow along a stretching horizontal plate with a magnetic ¯eld, viscous dissipation and chemical reaction are taken into account. A system of partial di®erential equations (PDEs) governs the °ow problem. Using dimensionless variables, system of governing PDEs is transformed to dimensionless form. Finite di®erence method is the numerical method adopted for solving the system of PDEs with initial and boundary conditions. The impact of potential variables is examined and displayed graphically. The results suggest that greater Hartmann number reduces velocity and temperature, whereas raising chemical reaction parameter decreases concentration pro¯le. Moreover, skin friction increases with Hartmann number values and Nusselt number, showing increase for growing Eckert and Prandtl numbers.
