【発明の名称】境界層制御用の多電磁タイル
Document Type and Number:
Japanese Patent JPH08512119
Kind Code:
A
Abstract:
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 the fluid a magnetic field B having flux lines along the surface of the wall and an electric current density J traversing the magnetic flux lines in the fluid to form a control region. The magnetic field B and the electric current density J create in the control region a force J X B that can stabilize or destabilize flow in the boundary layer. A plurality of such control regions can be arranged in a two-dimensional array (300) of control tiles that are periodically actuated in a controlled, predetermined pattern at a critical frequency that provides boundary layer control over a given area.
