Abstract EN
The effects of a background uniform rotating magnetic field acting in a conducting fluid with a parallel flow are studied analytically.
The stationary version with a transversal magnetic field is well known as generating Hartmann boundary layers.
The Lorentz force includes now one term depending on the rotation speed and the distance to the boundary wall.
As one intuitively expects, the rotation of magnetic field lines pushes backwards or forwards the flow.
One consequence is that near the wall the flow will eventually reverse its direction, provided the rate of rotation and/or the magnetic field are large enough.
The configuration could also describe a fixed magnetic field and a rotating flow.
