Hypersonic stagnation-point boundary layers with massive blowing in the presence of a magnetic field

Abstract

The effect of massive blowing rates on the steady laminar hypersonic boundary-layer flow of an electrically conducting fluid in the stagnation region of an axisymmetric body with an applied magnetic field has been studied. The governing equations have been solved numerically by combining the implicit finite-difference scheme with the quasi-linearization technique. It is observed that the effect of massive blowing rates is to remove the viscous layer away from the boundary, whereas the effect of the magnetic field is just the opposite. It is also found that the velocity overshoot increases with blowing rates and also with magnetic field. The effect of the variation of the density-viscosity product across the boundary layer is strong only when the blowing rate is small, but for the massive blowing rate the effect is negligible.
