Unsteady nonsimilar shock-induced laminar boundary layer on a flat plate with magnetic field

The effects of magnetic field and mass transfer on the unsteady nonsimilar laminar compressible shock-induced boundary layer have been studied on a flat plate with variable gas properties. The governing nonlinear partial differential equations with three independent variables have been solved numerically using an implicit finite-difference scheme. Computations have been carried out for accelerating and oscillating flows. The results show that the skin friction and heat transfer respond significantly to the time-dependent free stream velocity. Also, magnetic field, surface mass transfer, velocity of the wall and wall temperature have strong effects on skin friction and heat transfer, whereas the effect of the variation of the density-viscosity product and the electrical conductivity on them is rather weak. The magnetic field reduces the heat transfer, but the skin friction is increased.
