Electrofluid Dynamics Energy Conversion Research.
Abstract
Electrofluid Dynamics (EFD) is a method of direct energy conversion in which the energy contained in a flowing gas is converted directly into electrical energy. This is generally accomplished by seeding the flowing gas with unipolar charged ions produced by a corona discharge from a sharp grounded electrode. The unipolar ions typically are deposited on particles usually produced by condensation of either a minor component (such as water vapor) of the flowing gas or by condensation of the flowing gas itself. The charged particles are then transported by viscous interaction with the flowing gas to the collector electrode of the generator where at high potential the particles release their charge to the collector. The current thus generated travels through a load to ground. Many references can be cited which describe the basic operation of various EFD generators; several are listed in the Bibliography.
