Electrogasdynamic generators

Recommended Posts

I'm trying to understand what the perspectives electrogasdynamic generators could have.

And have questions to those who understand the principles of their work quite well:

1) What are their efficiency, power density and electric current density limitations? What could be done to improve these parameters? 

2) What kind of a charge balance between negative and positive charge quantity is there typically? Is there the same amount of positive and negative ions or there could be a large disbalance? If negative ions created by corona discharge move from emitter to collector, then in what direction positive ions do move? Could EGD generator work efficiently if only a lot of negative ions form in the duct, but no positive ions there? In other words if there exist a large charge disbalance in a working fluid?

Like you, I tried to understand the essence of this question (it was not possible to find out something specific), but there are serious obstacles to understanding what you are asking (perhaps if you could provide sources of information, together maybe we could understand the specific parameters of physical processes in such devices):

1) it is necessary to find publications on the study of the charge distribution inside a dielectric, in particular, a gas.
2) Scientific publications on the phenomenon of the "cold discharge", in which the charge is transferred from the dielectric to the conductor and vice versa.

> Without a detailed instrumental study of these processes, it would be impossible to say something unambiguously logical and defined in this topic, since there is a significant gap in the education system in this topic (I have long studied physics and applied electrostatics in theory). In our time in the educational literature there are no such sources. At least in Russian)

> Does anyone study the phenomena of charge transfer through liquid dielectric media in which laboratory or university?
Are there any CAE software packages in which this can be roughly modeled?
