Abstract

In general, the present invention relates to methods and apparatuses that achieve high gas flow rates through the use of an electrostatic pump. According to some aspects, the present invention relates to additional, auxiliary electrodes that generate increased ion current at lower voltages, which leads to greater pumping power than a corona wind discharge. According to further aspects, the invention provides for a directional emission of the ions. This eliminates the back flow of ions and improves the electro-fluid power conversion efficiency and pumping performance. According to yet further aspects, the invention enables the electrodes to be fabricated directly on a dielectric substrate, making the system mechanically rugged and easily fabricated.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 014,694, filed December 18, 2007, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to electrostatic pumping apparatus and methods using ion generation, and in particular, to the use of novel electrode arrangements for creating ion generating regions without relying on small features of corona electrodes to concentrate the enhanced electrical field. Halo discharge. Background technique [0004] Electrostatic hydrodynamic (EHD) gas pumps, such as corona discharge gas pumps (ie, corona wind), typically include one or more pointed (eg, corona) and blunt (eg, collecting or neutralizing) electrodes. Application of an electric field between the two electrodes results in a localized breakdown of the gas near the pointed electrode, known as a corona discharge. The discharge produces ions that ...
