Abstract: | A numerical investigation is performed to study the MHD free convection flow past a semi-infinite inclined plate subjected
to a variable surface temperature. The Joule heating and viscous dissipation effects are taken into account in the energy
equation. The governing equations of the flow are transformed into a nondimensional form using suitable dimensionless quantities.
A fully developed implicit finite-difference scheme of Crank-Nicolson type is engaged to solve the dimensionless governing
equations, which is more accurate, fast convergent, and unconditionally stable. The effects of the MHD, inclination angle,
power law, Grashof number, Prandtl number, Joule heating, and viscous dissipation effects are studied on the velocity, temperature,
shear stress, and heat transfer coefficients during transient periods. It is observed that the MHD has retarding effects on
velocity. |
