| Abstract: |
An optimally loaded electrohydrodynamic power generator which provides a uniform maximum loading throughout an EHD conversion channel. The channel between the injector and collector is in the form of a slender, converging-diverging nozzle of a shape defined by the following pair of parametric equations: <IMAGE> <IMAGE> where r=nozzle radius at station z, r1=nozzle radius at throat, gamma =ratio of specific heats, M=Mach number at station z, lambda =characteristic length, z=axial coordinate.

| Claim |
What is claimed is:
1. In an electrohydrodynamic power generator of the type having an injector located upstream of the input to a conversion channel for injecting charged particles into a fluid stream to form a charged aerosol flow through said conversion channel, a collector located downstream of said injector to remove said charged particles and an electric field impressed across said conversion channel which opposes the fluid motion, the improvement being a converging-diverging conversion channel wherein the section of said channel downstream from the injector has the geometric shape defined by the pair of parametric equations: [Figure] where r=radius at axial location z,
- r1 =radius at nozzle throat,
- .lambda.=longitudinal characteristic length for the fluid stream,
- γ=ratio of specific heats,
- M=Mach number at axial location z, and
- z=axial coordinate.
