An eleotrofluiddynamic high voltage generator has been built using a liquid dielectric fluid. The device, often referred to as a fluid Van de Graaff generator, has a high internal impedance and produces a maximum voltage of between 50 and 60 KV at a current of 1.5x10-6 amps.
The effect on the device output of varying several of the system parameters was examined, and it was found that varying the ionizer supply voltage was the best method for controlling the output current. Two factors, in particular, limited the output of the device, the fluid flow rate and the ionizer design. The problems of fluid contamination and fluid leakage caused the greatest experimental difficulties.
