The boundary layer of a fluid travelling in a mean-flow direction relative to a surface of a wall of a body is controlled by generating in a near-wall region of the flow a magnetic field B having flux lines parallel to the surface of the wall and an electric current density J traversing the magnetic flux lines in the fluid. An electrolyte or other conductivity-enhancing material is introduced into the flow to provide an electrical conductivity gradient in the near-wall region. The magnetic field B and the electric current density J create in the fluid a ...
1. An apparatus for controlling a boundary layer in a flow of a fluid having a predetermined electrical conductivity and moving relative to a surface, said apparatus comprising: conductivity altering means for providing an electrical conductivity gradient in a near-wall region of the flow proximate to the surface; magnetic field generating means for generating in the near-wall region of the flow a magnetic field B(x,y,z,t) having flux lines with a predetermined orientation with respect to the direction of relative movement of the fluid and the surfac...
