20080277004 | Inlet Electromagnetic Flow Control - A method to manipulate boundary layer conditions within a ducted fluid flow is provided. This method may be used to attach fluid flow to ducted surfaces bounding the fluid flow. This involves flowing a fluid over the surface wherein the fluid contains positively charged ions and electrons. An electric field accelerates ions and electrons in directions parallel to the electric field. The accelerated positively charged ions accelerate low energy air within lower regions of a boundary layer over the ducted surfaces bounding the ducted fluid flow. A magnetic field at the surface redirects ions and electrons based on their velocity and charge. The magnetic field imparts little force on the relatively heavy and slow moving positive ions but has a significant impact on the relatively fast moving, light weight electrons | 11-13-2008 |
