STUDIES IN MAGNETO- AERODYNAMICS .I. ONE-DIMENSIONAL FLOWS. II STABILITY 07 LAMINAR BOUNDARY LATE R

摘要

The governing equations of magneto-aerodynamics are examined for the weak interaction approximation. It is found that for the case where RVRH<<1 it is possible to treat the magneto-aerodynamic inter¬action as a simple additional body force. Accordingly, the approximate equations for weak interaction are derived. These are applied to several simple one-dimensional flows such as the propagation of small disturbances and one-dimensional channel flew.nThe stability of incompressible laminar boundary layer on a flat plate with the presence of a transverse magnetic field fixed with respect to the plate is considered in Part II. It is found that for this case the effect of the magnetic field is to de-stabilize the boundary layer, caused mainly due to the modification of the mean velocity profile by the magnetic field.
